No, it's rather essential. Imagine someone wants to create a fork of LilyPond,
where he directly links to gs instead of calling the binary. He'll be out of
luck, because gs is GPL v3(+?), while LilyPond is GPL v2only. The "or later"
allows to link GPL v3 libraries...

You can't simply go around and change licenses, unless you are the copyright
holder! That's the paperwork that is needed: Every contributor, who has until
now contributes as GPL v2only, needs to agree to change his/her contributions
to GPL v2+. Unless you track down every substantial contributor (git helps in
that regard), LilyPond can't switch to GPL v2+.
Cheers,
Reinhold
