I'm wholeheartedly against racial abilities that improve with level other than ones that are a number based on level (such as save DC). You don't see any of the core races improving their abilities over time - that's left to the classes.
I also share the opinion that racial feats are the way to go for any sort of ability you do want to improve over time - they represent a sacrifice in order to get the racial benefits, rather than simply a bonus that comes from having chosen that race initially. Racial feats can also have character level minimums to ensure that any abilities gained through them do not appear until those abilities are already appropriate/expected for a party of that level.
