So, in addition to several other reasons* why I dislike how the playtest handled half-elves and half-orcs, a major concern of mine is how Paizo will handle adding more heritage feats after the CRB.
I'm assuming, at least, that they will add more heritage feats. There may not be specific plans for it yet, but it would surprise me if over the entire course of PF2, they were content to not add more.
Right now, having four options for heritage feats if you want to be a gnome, one if you want to be a half-elf, and two if you want to be a human feels somewhat weird, and it feels uncomfortably less customizable to me to play a half-elf or half-orc. But that's only going to get worse, say, once we have nine options for heritage feats for gnomes, five for regular humans, and one for half-elves. Which is kinda lame, especially since heritage feats are imo an amazing way to handle stuff the different aasimar/tiefling/changeling/dhampir/etc variants. And not a great way to make an impression on new players when that's half the way they can customize their character by ancestry for the first quarter of the game.
Unless Paizo's plan is to just expand them anyway. Which also feels awkward to me, imagining a list of human heritage feats needing different individual feats allowing you to be something like five different kinds of half-orc, five different kinds of half-elf, four different kinds of dhampir, etc. And then six kinds of aasimar, six kinds of tiefling, eight kinds of changeling... it sounds like it would be much tidier to give the PF1 races their own ancestry and their own list of feats.
I guess it's Paizo's game and if this is how they want to handle it... but if it's something feedback is wanted on, personally I question whether anyone who actually plays those races is in favor of it.
*(having to use half a feat on knowing a potentially native language originally, post-update not necessarily being able to access it at all without a non-ancestry feat, the "free" heritage feat imo increasing how mechanically inferior a choice it is to Versatile Heritage or Skilled Heritage, and it just plain not feeling as fun to play a human with the Half-Orc heritage feat)
