Because upgrading from perl-5.10 or perl-5.12 to perl-5.14 is a very
different proposition to upgrading from perl-5.10.0 to perl-5.10.1
(which is the sort of change where perl-after-upgrade is useful.)
Principally there's no guarantee of binary compatibility for loadable
modules across that large a version bump. As quite a big proportion of
perl modules do involve loadable shared object code, which will have to
be recompiled, it is simpler to just recompile everything
