Let's say you add a feature and bump the version number. Another package
wants to use that new feature, so it requires the new version number.
Because seq.el is on Melpa, if the user had a previous version of seq.el
installed, there's no guarantee the user will be upgraded to the correct
version when he installs the other package.

This is a compromise people make and accept, in order to get the package
out there. But it's an unnecessary compromise if a package is already going
on Gnu Elpa anyways.
