5e feats are actually largely Bigger and Better than 3e feats. PF2 feats seem to have gone, in majority, the other direction.
Now, your second paragraph is right, but I'd prefer more erring on the side of "do something cool" than I am seeing in the PF2 feats. I at least FEEL like I get that from 5e feats, which, as you say, have to compete with ASIs.
Then again, I actually really LIKE Keen Mind, so my subjective analysis may be somewhat skew from yours in terms of judgment criteria.
I was going to say that the strength of the Ancestry structure is that the half-orcs might get back their stronger alt-features in later feat releases, but to learn they can't even have DARKVISION before level 5 is...buh?
Okay, I get it: there's a running gag at this point that darkvision is so common (in 5e, but also in 3e and PF) that humans and halflings are actually DISABLED for lacking it, rather than the other creature types having a special ability by having it. This does make that shift back, since now nobody has it before 5th level, and only a subset of orcs above 5th level will have it. Cool, sure, fine.
But...yeesh.
