In MediaWiki-extensions-CommunityConfiguration, client extensions register their providers like this:
"CommunityConfiguration": { "Providers": { "Mentorship": { "store": { "type": "wikipage", "args": [ "MediaWiki:GrowthExperimentsMentorship.json" ] }, "validator": { "type": "jsonschema", "args": [ "GrowthExperiments\\Config\\Schemas\\MentorshipSchema" ] }, "type": "mw-config" } }
Since https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CommunityConfiguration/+/1015078, we're referring to the Mentorship as the ID (key under which the provider is registered), and to whatever the communityconfiguration-LOWERCASE-ID-title (so in this case, communityconfiguration-mentorship-title) message resolves to as the name.
However, this refactor was not done in CommunityConfiguration's frontend and PROVIDER_NAME still refers to the title, not name. This causes confusion, as name means something else in BE and FE. To ensure CommunityConfiguration stays maintainable, this should be fixed.
