Stable versions is Wikipedia's answer to
everything.
Dangit, I thought Wikidata was the answer to everything!
(Or Semantic Mediawiki, which seems to be the currently active name/project:

I've been telling Wikipedia critics "stable
versions
could potentially improve situation X" for _years_ now
Ditto, but for Wikidata.
Hopefully coming soon?
