Just like with package archives in the GNU/Linux world, this is useful
if the version numbering across those archives is incompatible even
though they are supposedly serving the same packages.  Priorities are a
good way for a user to describe in which order he wants multiple
archives to be searched for updates and have been used for this purpose
elsewhere.

MELPA has choisen their incompatible version number scheme deliberately
and I don't think they are going to stop using it.

That would not help since it would still be interpreted as a higher
version than the released package and be an update candidate.
Priorities do not need coordination among package archives.
