I think the whole thinking is flawed. The strategy agreed between the car makers and the FIA is dead set against allowing further performance developments in engines and aero. both fields are supposed to be frozen. no more power, no more downforce! full stop.
engines and aero are supposed to compete on an efficiency basis and the main force of development is supposed to be regenerative energy and low drag aero. I do not see an alternative to that strategy and the sooner people realise it the better. in the future F1 cars will win races if they have higher efficiency squeezing power from where other cars loose energy. to deploy this strategy other sources of advantage have to be blocked. it sounds a bit harsh but thats what we are going to see.
That's a dark view, but I do not wholly disagree with your interpretation. More to the point, that's not a bad reason for M-B and others to NOT want a team in F1. Here in the US, M-B in particular are pushing their AMG models, trumpeting their HP - not efficiency or aero or environmental awareness - just brute HP. That sure does not fit the F1 described above.
