Another dubious "rough consensus", and not something I recall. The
discussion was about *allowing* a kind of "share alike" restriction,
and a poll resulted in a "clear tendency" to not offer that option.
The poll didn't examine the reasons like "certainly very complex to
define" or "likely a bad idea". In the CC model it's not complex
to add a "share alike" to a given "CC-BY" resulting in "CC-BY-SA".
A simple fix could be to remove the complete statement, and let the
WG Chairs say something about the discussion in the questionnaire.
