But none of this was exactly the concern I raised. My concern was that the TOS proposed for WMF site would restrict authors to using to certain facet of the CC-by-SA license that is not commonly used. This would generally prevent anyone who was not an author from importing externally published CC-by-SA material which likely relies on a more common facet of the license (naming the author by name). This is because such non-authors would have no right to agree to the more restrictive WMF TOS on behalf of authors who simply released their work as CC-by-SA.
This is explicitly addressed - the proposed terms do make allowance for content attaching additional attribution requirements; see the section "Attribution of externally attributed content" in: http://meta.wikimedia.org/wiki/Licensing_update
What is and isn't acceptable in terms of additional attribution for external content, and how such attribution should be displayed, is IMO something we need to work out as a community. We don't need to solve every problem in this process; fundamentally what we're trying to do is create a consistent baseline that's understandable and easy to build on.
