Canonical interwiki prefixes/Proposed extension
It is proposed that a site, e.g. WikiIndex, have an extension that does the following:
iw_modifiedfield to interwiki table; this will be the timestamp of when that row was last modified.
interwiki_deletedtable; this will track interwiki prefixes that have been removed from the interwiki table.
interwiki_conflictedtable; this will track interwiki prefixes that are inactive because they conflict with a prefix that is currently active in the interwiki table.
iwstartparameter to API so that the user can retrieve interwiki modifications starting with a particular timestamp.
