If you're waiting for an official response from the rules team, then you will probably be waiting a while.
But one example: the Perfect Aid ability grants additional bonuses to "your ally" when you use the "aid another" action. Since you can't use the aid another action to give yourself a bonus, it doesn't work to grant yourself a bonus. The cavalier's Aid Allies ability is similar. In neither of those situations does it make sense to count as your own ally.
The Lend Judgement spell lets an ally benefit from one of your active judgments. Again, it doesn't make sense for that ally to be yourself.
More significantly, the murderous command spell causes a creature to "[attack] its nearest ally." As it is always closer to itself than to anyone else, that would always cause it to attack itself if it counted as its own ally. I consider this to "not make sense" for two reasons -- one, spells to compel suicide are much more powerful than first level, and second, if it was supposed to be a suicidal command, saying "attack itself" would be much more straightforward than "attack the nearest enemy, which is always itself."
