I don't think this one is practical, since things are often implicitly
abandoned by e.g. people changing jobs or changing their focus etc and
under such circumstances they are unlikely to take any explicit action.

Yes, and I suppose based on data mining you can see the longest delay
before "coming back to life", which would then feed into the selection of
the certain period.

As I just said in another reply, it would be interesting to know what the
incoming rate of these were, there's a chance it might not be too bad once
some simple matching heuristics have been applied to weed out the simple
tweaks to the commit subject.
