In one way certainly, but not necessarily for future proofing.

Certainly, but we have to trust the FSF to keep the GPL "right" now if we go 
with the any future version option.

There are benefits and costs either way you do it.

I think the only way around it would be to enact copyleft into law worldwide. 
Make all works default copyleft. Make those who want a copyright instead of a 
copyleft mark their works as copyright.

That should fix the need for trying to find workarounds for copyleft 
incompatibilities.

all the best,
