The way they're doing it actually seems way better in my opinion.
Steam's userbase is big enough, there's likely always an exact system out there that's shared fps for the game you want and with that info you can know (with some margin for error) how it'll run for you.
Game minimum requirements aren't always accurate in my experience and I'm guessing they list actual components rather than specs of said component because two chips with the same cores/ghz can perform quite differently nowadays, so they leave it to the consumer to validate (might not be easy or possible to calculate this type of thing programatically im not sure).
