What do you mean by "first"?  We already support the likes of
"28.3 Beta3", and "Beta3" is not ignored there as some free-text

And that is assuming the developers of 3rd-party packages can have
some reasonable way of associating their versions with Emacs versions,
which I still think is a problem with no solution.
