If you'd ask me, "open file, drop privileges" is a sensible thing to do,
and pushing such patches upstream is even better, because it will
instantly offer increase in security for all the downstream users
without any work on their part (even those who install programs manually
will benefit).

(Other security concerns, like an exploitable game being able to read
and write all your home directory is more of a pressing matter though).
