A few years ago, I wrote a "yet another" client library for the MediaWiki action API, and went to the official list on https://www.mediawiki.org/wiki/API:Client_code , expecting to add my library. Instead, I found instructions on that page asking that new libraries be added to https://www.mediawiki.org/wiki/API:Client_code/All and describing a review process for periodically checking that libraries meet some basic standards, before copying them over to the main list.
As happens with wiki workflows, this excellent concept fell into disrepair and with nobody pushing it forward, there seems to be no new review activity. Without active curation, I think it's unhelpful to have two separate pages for "reviewed" and unreviewed libraries. My suggestion is to merge the two pages and add a column for review status, so the information is all in one place. I imagine this will reduce the work needed to maintain this list.
