For this purpose, it doesn't matter -- we're only interested in the
major version.  But if you want to expand the language in a more regular
way, then a different separating character (between the part we parse
and the one that's free text) can be used, of course.  Semicolon?

They don't really need to.  They decide "we think people with Emacs 25
shouldn't have this in their M-x TAX" and then put "26.1;Magit/1.2" in
the string.
