The same could be said for a lot of the feats throughout the game. There are quite a few that feel like they should be able to be had by anyone--or at least a subset of races (half-orcs with razorteeth for instance). And not just ancestral feats--there's quite a few class feats that I'd argue more than make sense being used by at least some other classes.
It's a tough thing to come up with feats that describe one particular thing and only that thing.
I'm finding the opposite effect. Because general feats have the adopted ancestry, every race has access to almost all the ancestral feats, and humans have natural ambition so its very easy for any race to be almost anything or have access to more class feats
adopted ancestry->human->natural ambition->extra class feat
even ancestral feats that are normally locked at 1st level behind half-race feats like orc ferocity can be picked up by humans at level one.
human->general training -> adopted ancestry-> half-orc-> orc ferocity
This is a great pick up for a human barbarian.
But baked into the feat is the idea that the character has been raised among some other group and picked up some feat that's ethnically 'not their own'. Which is basically to say that no human or elf...or halfling even could be Very Sneaky without having been raised by goblins. And that just seems wrongheaded to me.
