How long has Google store been operating (under various names)? Over a decade I think. Do they know people would love to choose between apps with and without ads? Of course. Why they decided not to implement it in the listing? Because they live from ads. There is exactly zero chance they will do it as you propose.
It would be so easy to implement, it seems scornful not to. When I want a needle, they hand me a haystack and say "we etched 'this is a needle' into the needles for you so you'll know when you find one. Good luck."
I admit I haven't used android for three or four years so maybe they have this capability now, would love to be corrected if so.
