Oops. You know what? This might very well have been me.

I remember hearing about the license name change, and applying it to the new 
files I was writing, and I didn't know that it came with a version number 
increase as well. In fact even now I wouldn't really have been sure about the 
fact that Library=2 and Lesser=2.1.

Technically I'm not sure, e.g. I thought this was version 2 renamed.
However I never heard of someone agreeing with LGPL v2 and disagreeing with 
v2.1. And your next paragraph is an even bigger reason for going ahead:

Well, in that case that's even explicitly allowed, then.

Being pragmatic, I would say yes. I really can't see a KDE contributor coming 
back and saying "I wanted my code to be 2 only, not 2.1", given that the only 
relevant difference between these two seems to be the license naming 
(according to wikipedia; I didn't do a diff ;).
