Pretty much, yes. Since they necessarily link to Emacs's own code which
is GPLv3+, you have to use a license that's compatible with GPLv3+.
Note that GPLv2+ is one such compatible license (as opposed to GPLv2).

No, they're GPLv3+ (most licenses out there implicitly say "this version
or any later version of it", whereas the GPL is more strict and you
have to explicitly say "GPLv2 or later").

If it's stritcly "GPLv2 and no later" then it's probably an error.
