The assumption is that someone would immediately apply the FC4
updates, fixing the hole.

But think of fixes instead of security patches.

Consider that -5 had a change to make the package buildable on FC4,
that would break on FC3.

Issuing -5.1 (or 6, for that matter) for both FC3 and FC4 implies it's
newer than 5 for FC4.  Should someone depend on the patch that made it
buildable for FC4, and say so with a Requires: foo >= 1.2.3-5, issuing
the errata as -5.1.FC3 might incorrectly satisfy the requirement.

I still think they should be used for the 0.<buildid> case, for *any*
extras that might ever make it to the core (i.e., any extras at all
:-)
