Is there another reason for GPL-2+ than just compatibility?
Because I quite find the "or later" thing to be quite a scary one as 
whatever will come up next as a GPL will become applicable and it feels 
quite weird to me to have a license that can evolve to whatever 
license over time.

I think I would personally slightly prefer to have it be properly
dual-licensed GPL-{2,3} or GPL-2 & CC-BY-SA-4.0 instead.
