  -----------
  [NFC] Use Optional<ProfileCount> to model invalid counts

ProfileCount could model invalid values, but a user had no indication
that the getCount method could return bogus data. Optional<ProfileCount>
addresses that, because the user must dereference the optional. In
addition, the patch removes concept duplication.
