For https://gerrit.wikimedia.org/r/#/c/196981/ T85847: Grant editcontentmodel right to all logged in users please update/add any needed onwiki documentation, e.g.
- Add a translatable help page for end-users explaining Special:ChangeContentModel (how it works, common use-cases for each of the available contentmodels, (planned use-cases?), how to revert mistakes/vandalism)
- Add info for devs, on how they can use it
- Update https://www.mediawiki.org/wiki/Help:Extension:MassMessage
- Possibly it should (?) be explained at https://www.mediawiki.org/wiki/Manual:ContentHandler or one of the linked pages
- ?
From a glance around, it looks like there are some details in the comments at T72592: Implement a user interface to change a page's content model when $wgContentHandlerUseDB = true;
