@JStrodt_WMDE found https://meta.wikimedia.org/wiki/Gadgets/wikipedia/default, which lists `referenceTooltips` in upper and lowercase. This conflicts with what we found before via {T234204}.
[] Run some script and create an up-to-date list of wikis where `referenceTooltips` is lowercase.
[] Look for other names with a regex like `/.*ref.*tool.*/i`.
[] Update configuration with what we found.
Implementation
# Iterate over [[ https://www.mediawiki.org/w/api.php?action=sitematrix | all wikis ]] ([[ https://www.mediawiki.org/wiki/API:Client_code | API libraries ]])
# Search through the gadgets of each wikis using the gadget API ([[ https://en.wikipedia.org/w/api.php?action=query&list=gadgets&gaprop=id%7Cmetadata%7Cdesc | example ]])
# Look for the gadget in each wiki:
# Option 1: Find the ReferenceTooltip data by applying loose rules which match against script and style files, and gadget name. Overcollect rather than undercollect. Look for other names with a regex like `/.*ref.*tool.*/i`.
# Option 2: We can build the list by requesting raw source for MediaWiki:Gadgets-definition and searching for ReferenceTooltips.js. It's also possible that the javascript file has been renamed.
# Store data (wiki, referenceTooltip installed: true/false, enabled by default: true/false, custom name) in a suitable form.
