At the most recent meeting of the engine working group last Tuesday it emerged that constructors are looking for an engine formula that will provide simpler and lighter engines, following a considerable weight increase since the introduction of the Hybrid power units in 2014.
Since Porsche haven't committed, nor any other manufacturer, for 21 and the new rules the current manufacturers are questioning why they would have to build completely new power units and still be the only 4 manufacturers in F1.
Basically, it's up to Porsche to put up or shut up.
On the other hand Porsche is the only possible new manufacturer that attended all af the '21 engine meetings. Also it's not about "beeing able to build an h" but "being able to build a competetive h until 2021" and with the latest move Fer/Merc/Ren simply ensured that the '21 regs will not be finished soon and so directly shortenend Porsches development time.

And I believe the peak power of the V8s was quite a lot less than 900HP which is more the level of the 3l V10s.

For the engine cartel standard part h would be the same than removing h. Bit unsure about Renault, but for the other two h is simply a performance differentiator they do not want to loose and I think it's about hindering porsches engine development towards 21.

As an aside, Porsche is part of VAG, the largest car manufacturer in the world. They have a heat energy recovery system on the 919. If they can't develop an MGUH under the current rules, there is something wrong.
You can't expect any manufacturer to commit to a set of regulations that doesn't exist yet.
And yes, Porsche might be perfectly capable of making an MGU-H unit, but no matter what, they are still going to be 6-7 years behind in development compared to those who are already in F1.
Just look at Honda and how difficult it was for them, and they entered only 1 year behind the others.
As much as I enjoy the technical aspect of the MGU-H, it just doesn't contribute to good racing. It's too complicated, and robs a lot of engine sound. It might be a technology more fit for endurance racing IMO.
MGU-H has nothing to do with reduction in sound it is not a consecquence to engine sound. if anything when its playing its part it contributes to thev sound.
How about PU, drivetrain and cooling must fit in a determined swept volume with a predetermined amount of fuel to race 305km?
The type of propulsion is up to manufacturer as long as it fits in that volume... Manufacturers follow their technology path. 5 years to develop the tech then race it.
Pistons may be larger than ideal. 533cc vs 300cc for the 2.4L V8s and 3.0L V10s.
Mandate 50cc naturally aspirated cylinders of any quantity. 26k RPM should reasonable for such a small piston. To reach familiar power levels, a small sum of fifty-eight cylinders may suffice. Which leaves us with a leisurely 12.5 kHz exhaust note. Which is 8x better than that old V10 note, so the purists should be octuply satisfied.
Just don't go over eighty-four cylinders or else they'll complain about the engines being too quiet again.
And I believe the peak power of the V8s was quite a lot less than 900HP which is more the level of the 3l V10s.
Ok then. if the 3l v10's had 900HP, why wouldnt the 3.2l v6 have similar/more?
No reason at all why they might not peak at that, but average over a lap would be less than today’s. And they would need to carry 70 or 80 kg more fuel to do so.

...and 20kg less battery means refueling comes back!!

Refuelling went away because of safety and the cost of shipping 20 refuelling rigs around the globe. How does 20 kg of battery change things?

Space for the battery to increase the fuel tank size.
And, we can go crazy and move to CNG in hot-swappable "pods" that are the size of fire extinguishers.
PS: they still have refuelling rigs, just not the Spec ones that used in races.
How much time is gained by a 200Kw KERS system per lap? The MGU-H is major source of recovered energy, twice as much as the MGU-K’s brake recovery. Without heat recovery, the benefit of a KERS will be hardly greater than the time lose for extra cooling, weight, complexity, etc.

There will also be the weight of extra fuel to replace the recovered energy.
