That is great. One can probably craft a MediaWiki extension to have the
metric shown on the Special:Statistics
And lets be crazy, even add a statistic link in the sidebar for each pages!
https://en.wikipedia.org/wiki/Special:Statistics
The actual mediawiki work for this only really involves reading JSON and
throwing bugs at us if anything breaks :) So, should be easy, this was one
of hour hopes as well, let's get to it!
By the way, to even better support this (with more performance / easier
discovery), we plan on providing access to this api from the wiki-specific
RESTBase URLs (eg.
https://en.wikipedia.org/api/rest_v1/?doc). That hasn't
been deployed yet because we're discussing where the best place for it is
there (opinions welcome).
