However, there is something nice about knowing a balanced way to do x or y across the board and at different tables.

I don’t agree with this argument. Balancing is the job of the GM. Unless the GM acts as a glorified screenreader who only reads a pre-made adventure to the players with no influence what happens. But if the GM decides what monsters you run into, the GM has more influence over the balancing than the game framework. So why not lean into it fully and make the GM responsible for the whole balancing?

I mean, pen&paper RPGs aren’t a players vs GM game, but instead the GM plays together with the players to create an interesting experience where everyone has fun. No need for the framework to do balancing, because a good GM will do that.
