To get some numbers on the adoption of the Reference Previews feature it would be helpful to have data on how many users have the competing gadgets enabled before and after deployment.
- Look at the list of gadget names on the wikis for ReferenceTooltips and NavPopups ( wgPopupsConflictingRefTooltipsGadgetName & wgPopupsConflictingNavPopupsGadgetName )
- Get the number of users with this gadget enabled for wiki, by querying the database. See https://gerrit.wikimedia.org/g/mediawiki/extensions/Gadgets/+/2dda194930cc5844f832d02b87797a057989604c/includes/Gadget.php#259
Most current list of gadget names can be found
