In the long term, wiki.musicbrainz.org should be moved to wiki.metabrainz.org but to achieve this goal wiki pages related to MusicBrainz have to be identified as such. A way out would be to move those pages under a new namespace "MusicBrainz:" similar to the current namespace "MetaBrainz:".

However doing so would break the documentation pages in MusicBrainz website, that's why it depends on deploying a solution such as MBS-13101 at first.
