If folks only have 5E experience, I guess I could see this. The thing about PF2 is once you start making decisions (ancestry, background, class) your feat pool narrows greatly. At level up its pretty easy to find the 2-3 feats that apply, and then decide on the one that helps you. In the past, you just had a mountain of feats to choose from and perquisites was the only limiter.
Yeah, the siloing of feats by type and level really means that getting worked up about the total number seems odd to me (though that said, you can have a situation where you're looking back at lower level feats because the current level ones are either impossible or uninteresting; I had that happen a couple times with my current character).
