I think this is not too important.
IMHO any bug-specific migrations(as XWIKI-1468-B) in xwiki-platform-core
is bad. Because:
it is decrease performance
fast to obsolete
pollution core code
If we really need migration maybe we need create migration system.
Something like: store data version in db, xwiki will execute migrations
at boot. Migrations will be like patches from one data version to another.
(XWIKI-883 also need migration)
WDYT?
