Actually, it became a de facto standard in the community to differentiate 
between strict GPLv2 and "GPLv2 or later" (I guess we should thank GPLv3 for 
this...)

Googling for the "GPLv2+" term will show many OSS projects clarifying it this 
way. As well as many project catalogs and listings grouping by "GPLv2+" vs 
"GPLv2"...

In OE we've been using this term for some time now. Although, still too many 
old recipes use old notations, sometimes even as generic as just plain "GPL" 
w/o specifying the exact version. It wasn't as critical before, but these days 
OE is being adopted in corporate environments and proper licensing became 
quite important.
