Not really. I don't insist on it in code that I have only minor contributions 
to, but I will probably insist on code that's originally by me, or to which I 
otherwise have made large contributions.

No. v2+ requires the "or later" clause to be present. v23-only requires it not 
to be present. On is not a subset of the other. They are conflicting, and there 
needs to be arbitration in any given library or app so that the library or app 
as a whole can be relicensed to the same set of licenses.

Sure, it's not what both licenser-holders wished for, but the only non-
conflicting choice.

Thanks,
Marc
