Yes and no (to both questions).

I have been looking for a silver bullet that avoids having
  (a) something in the post-install target plus an @exec and an @unexec
      and thus redundancy, or
  (b) two extra scripts and thus two extra files in the port.  

Alas, I failed at that, and Emanuel convinced me that apparently there
is no way to avoid one of these two deaths.

That looks like a nice project for someone to improve our general
infrastructure along these lines.
