That's a good point. So waiving BY isn't transitive, and therefore is not 
like ~BY for derived works.

IANAL, IMHO:

Attribution and requiring source are separate issues. Requiring source as a 
non-license request is possible but innefective. That is, I can politely ask 
people to add source, but if they don't I can't do anything as it isn't a 
condition of the license. If they do so, and if they do pass on that request, 
peole are still free to ignore it.
