Following the recommendations in T370879: Investigation: How to best support custom footnote marker groups in VE, Parsoid, and read mode? (TBD: still to be discussed), we should build a community configuration (feature home, extension, docker-dev module, local example) page. Our first use case will be a selector for the backlink labels, because the default is generally undesirable, and conflicts badly with subreferencing.

• Can we use Codex for the Special page UI? Yes.
• Rough design for admin page.
• Discuss concept.
• Fixed list of supported symbols. This can be incomplete for now and improved iteratively in follow-up work.
• Show preview of backlinks (dynamically generated in JS, not using parser). List of alphabets comes from PHP, probably through setJSConfigVars.
• Has no effect until the config page is saved.
• Behind a boolean feature flag $wgCiteCommunityConfiguration, default is disabled, hidden and inaccessible.

Out of scope:

• Save and load community configuration
• Override legacy backlink customizations for real (with fallbacks)
• CLDR alphabets
• Search mechanics, eg. type locale or name or language
