@andy Can I ask what I'm missing? 'Cause I know you're not alone; I just want to understand your opinion better.

I'll happily agree that WotC put out too many feats in too many sourcebooks, and Paizo didn't help (by making a million more, and giving character more of them). But to me the solution would be to just use the core ones, and if you include some from other books limit them significantly in some way, not to switch systems altogether.
