I agree with this. At least one extra heritage or racial feat would be ok with me. Absolutely no more than three though.
Another thing I'd like to propose (and do a small write up on), is let the ancestries have more inherent traits (ie things like resistances and weapon specializations) but create and allow the racial feats that we select build upon what we have.
Like for the Dwarf for example. Allow us to pump up the Weapon Familiarity feat at later levels that give you more bonuses to your strikes or reduces the multi strike penalty sustained for multiple strike actions. Or Mountain Roots which likewise can either increase the bonus, or allow it to be used in other scenarios. Like shaking off charm or enchantment spells (Stubborn these hardy folk are)
These are amateurish examples admittedly, but I feel this method gives a lot more 'Growth' to the feel of your character as it levels; and also makes your ancestries feel more unique.
