Review boards that should be maintained by volunteers, are they active? If not, just redirect to mw.org. If community doesn't want centralisation, make it very obvious that the page is no longer watched by WMF staff (maybe also update user page). For certain communities with a particular visual editor configuration, a different engagement model may be offered.)
For reference:
Not centralized boards:
ar.wiki
en.wiki

Not centralized, but with explicit community commitment:
