What about a mechanism (in-doc comments or the like) that would allow 
existing authors to indicate that they're OK (or not) with a future 
upgrade to CC-BY-SA 3.0?

If authors on existing docs were encouraged to take advantage of such a 
feature/policy as opportunity invited, it'd lessen the work to eventually 
upgrade at least some existing docs, as well, tho it wouldn't help that 
much for those no longer involved, who would in any case need to be 
contacted manually before such an update.  But it would at least stop the 
problem from getting worse, and would incrementally ease the work 
necessary if someone eventually decided to actively try for an update.
