At the very least, it seems to empirically not be a
problem. The GPL has
included the "or later" language since it was first published in 1989,
and has since gone through two updates (the first in 1991), without, as
far as I can find, a single ruling invalidating that language. And
GPL-licensed stuff has *much* more extensive worldwide commercial reuse
than Wikimedia content does.
Indeed. It defies rationality to assert that there is a first-world
country where "or later" is an insuperable barrier. If you want me to
consider it one, I'd like to see an actual case please.
