I haven't been following all of this thread, but it seems a lot of the genesis 
of this license is the idea that there needs to be some sort of contract for, 
or license to, the non-copyrightable elements of the distributed code for the 
disclaimer of warranties and liability to be effective (at least, with respect 
to the non-copyrightable parts of the distributed code).  I'm not sure that 
that premise is correct, legally, although I can't say that with certainty (and 
I don't have the inclination to do a research project).

CC0 gives a complete (to the extent permissible by law) waiver of copyright 
rights, as well as a disclaimer of liability for the "Work" (which is that 
which copyright has been waived).  I believe that to be an effective waiver of 
liability, despite the fact that there is not copyright rights being conveyed.  
Does anyone believe that that waiver is ineffective?

OK, but wouldn't those changes mean that the license no longer applies to the 
uncopyrightable portions?  That would mean that downstream users would no 
longer have any protection from being sued, etc., right?

Thanks,
