If some people would prefer V10 but will watch F1 anyway, then
what wold be the point to cater to them, if it's otherwise undesirable?
It's the chance to see (hear) 18,000rpm V12s (which Toyota planned to return to in 2000 until banned, even at 3.0L let alone 3.2L or 3.5L where 12 cylinder may now very much be optimal for NA) that you wouldn't see (hear) anywhere else in motorsports.
10,000rpm Formula 3000 style V8? Be it Nicholson McLaren, Zytek, Judd, Mecachrome and so on they are a dime-a-dozen in hillclimbs and everywhere else (indeed the original Cosworth DFVs are a dime-a dozen too).
Small block American V8s? Everywhere.
Inline-fours? You betcha, everywhere.
But F1 racing would be only way to see wailing 18,000rpm V12s with pneumatic valvesprings -- which (IMO) are a lot whole lot of fun, given some folks already line the trackside fences for Paganis, F50s, Enzos, FXXs, Aston Martin WEC LMHs etc which are V12s which are not nearly that 'exotic'.
Even the historic V12 F1s don't rev to that (when they were new) and certainly not now when the durability is being conserved.
Don't forget the NA V12
IS the preferred engine layout of Scuderia Ferrari HP, Red Bull Racing Ford RBPT and Racing Bulls Ford RBPT. Given the example of WEC and their choice of a large NA engine there, it is very likely to be favoured layout of Cadillac F1 Team (and their subsequent customers) as well (as well as Aston Martin, though they don't make their own F1 engines yet).
As I've said, it would be logical to accompany re-banning turbocharging with doubling the current ICE size: from a 1.6L V6 to a 3.2L V12 (the FIA would probably reduce the mandatory Vee angle from 90° to 75° which better suits a V12 in conjunction with the turbo re-ban?).
If you ask me as a racer, I would love to have a V12 in the car for the noise and the sound and so on.

The purist in me would love to go back to a V10 that was done responsibly with sustainable fuel that reintroduced the sounds of grand prix racing.

Cadillac's comments are particularly notable:
When you start looking at turbo applications, everyone says ‘Oh, you know, turbos are more efficient and stuff like that. But combustion efficiency on N/A motors has gotten to a point now where it’s worth it to go with a naturally aspirated motor to save the weight of a turbo and intercooler.

That leaves only Mercedes, Audi and Honda preferring the hybridised, downsize turbo engine regulations. Which are only
half of the power unit suppliers.
Do Mercedes, Audi and Honda really outweigh the interests of Ferrari, Red Bull Ford and Cadillac? The two blocks are equal in numbers after all.
Crucially, Ferrari is the most prestigious constructor and holds the most political sway. Ferrari favours the NA V12 so much, they even still sell road cars with it and plan to do for as long as road-going regulations make it feasible!
As it is, Mercedes-AMG has already reverted several 63 AMG models from the inline-four hybrid powertrain of the C63 to a larger capacity ICE instead -- apparently in favour of increased saleability.
As below, Mercedes have confirmed the Mercedes CLE63 AMG will feature a twin-turbo V8 instead of the more efficient single-turbo inline-four with hybrid system from the Mercedes C63 AMG:
Dealer concerns and slow sales drive the return of V8 power to AMG’s mid-size two-door ...
After vehemently defending its decision to downsize its flagship ‘63’ powertrains from V8 to four-cylinder hybrid hardware, Mercedes-Benz has reportedly yielded to customer and dealer pressure and will release its upcoming Mercedes-AMG CLE 63 coupe (and cabriolet) with the German brand’s ... M177 twin-turbo 4.0-litre V8.

Are the Mercedes-Benz buyers and Mercedes-Benz dealers mistaken in their preferences which do
not align with industry electrification trends?
Will CLE63 AMGs with oversized ICEs and undersized hybrid system sit gathering dust on dealer storage lots (unlike hot-selling C63 AMG hybrids?), due to AMG's incorrect assessment of the sports coupe market?
[FWIW, it is really bizarre that the FIA use ICE cars as the safety car. The safety car should be switched to Mercedes AMG BEV and Aston Martin BEV models IMO. If they aren't fast enough or sufficient in range, that is the usual necessary compromise of electrification and must be accepted like the 2026 power units with less average power over a lap! But no reason not to aim for V12 NA ICEs for the Grand Prix cars themselves in say 2030, after the 2026-2029 power unit regulation set runs its course.]
