A thought just occurred to me - is there a way to know that priority pref
settings coming down via sync are pending, or complete? E.g. it would be nice if
there weren't pending settings to just start this immediately, or if the
settings arrived say after 8 seconds, to not have to wait the extra 7 seconds to
begin installing default apps. 

If this bug is urgent or that's a more complicated change than you want to take
on for now, that could certainly just be logged as a follow-up bug or something
(if you agree it's even a good idea).

Good idea, done.
