No sorry I explained my doubt badly.
I'm thinking of a project X licensed as GPLv3+ that after the release
of GPLv4 decide to move to GPLv4+ (as happened to many GPLv2+
projects).
This is fine and expected, unless Hydra manages to infiltrate FSF with
a couple of cool lawyers and to corrupt the text in some overlooked
way.
In this case, if after a couple of years Hydra start suing people
according to such overlooked detail, people would have a hard issue to
go back to GPLv3 without discarging all the patches provided.
A corner case, I know... but pretty in line with the Tentacle of Evil
theme... :-)
