Well, instead of using "or later" clause, one can
dual/tripple/multiple license code under licenses one is ok with.
E.g. GPLv2 | GPLv3 and _without and later_

But GPL text does confuse me as a whole, no modifications nor derivate
works of the GPL license text are allowed, and the original text has
"and later" clause - is licensing without "and later" constitues
modification of the GPL license text, which is prohibited and thus all
GPL licensed software is, in-fact, with "and later" clause?

I guess it's a more of debian-legal@ question rather than debian-devel@.
