In advance of SUL finalisation, $wgCentralAuthAutoMigrate being true will mean that when global users log in, we merge in any outstanding local accounts of theirs that are for whatever reason not migrated to the centre.
I don't know if this matters for Common/InitialiseSettings, but this is only applicable to wikis using SUL
Done earlier this month - see Gerrit change #62995.
