What would stop the fastest teams from doing their utmost best to qualifying last, thus getting the wanted top spot in sprint and sail away with the victory? Any metric used by FIA to identify or mitigate 'slowness' is going to be a shit-show as teams can offer up valid excuses, like 'this is not an exact science, we just had bad luck'
And then we have the biggest issue with this: this is a high performance sport, being first is literally the point. And you punish that by dropping these down the grid? You will find no driver in favour of this I would think.
No spec cars please, for the love of god!
Why do you watch F1? Perhaps some other form of automotive racing is better suited for you? I believe in the US they have spec cars, perhaps follow that and enjoy those races?
F1 is a sport where individual development as a team is key and also part of what makes F1. Why destroy F1 by making it essentially another US form of blending all to 1 level?
I will never understand F1 'fans' offering spec cars or reverse grids as solutions. Go watch another form of racing and you'll have all of that, enjoy. But try not to flatten F1 into a sport where performance and innovation is stifled.
