Could you point to the test in either license that prohibits modifying
license notices?
I certainly couldn't find it in section 2 of GPLv2, which seems to be
the relevant section.

Interestingly, 2.b seem to say that if I received a program under
GPLv2, and I pass it on, then I must pass it on under GPLv2-only...
So to be able to distribute something written today under GPLv3 (when
it comes into existence), you must be the original or have received it
directly from the original author....
