I think it should definitely count as a bug because what appears as
a "side-grade" might really be a downgrade because version NN.MM on GNU
ELPA corresponds to the commit where `Version:` was modified to "NN.MM",
whereas the built-in version may still say `Version: NN.MM` but with
various bug fixes and improvements installed since then.

[ The problem is yet more tricky with GNU-devel ELPA, because `Version:
  NN.MM` will lead to packages with version numbers NN.MM.0.DATE.TIME,
  so they will always appear to be strictly greater than the
  built-in version.  But least there, they should indeed be the
  latest&greatest, so at least it should be at worst a side-grade, not
  a downgrade (except for corner cases, like when the creation of the
  GNU-devel tarball fails for some reason, but this should be rare
  enough).  ]
