Why not? It's not adding any restrictions. If anything it's an additional 
copyright grant beyond what is in the GPL. As the author of the software I 
am entitled to relicense it under as many licenses as I choose.

People are always free to drop the "or any later" clauses from the derived
works they create.

But the phrase "or any later" is not in the GPL itself, it's something you 
place at the top of your own source code.
