"score" property for Q&A entities

In a discussion thread on this list a few months ago[1], there was
suggestion of adding a "score" property to Question/Answer/Comment (Q&A)
classes, alongside the existing "upvoteCount" and "downvoteCount"
properties.

As I'm currently marking up Q&A pages that display only a score (and not
counts of individual upvotes and downvotes) [2], this would be a useful
property. Did the discussion ever turn into a full proposal?

Thanks,
Alf
