AD FSMO role transfers are generally for the case where a DC is really
gone away, not for automatic transfers.

The reason for this is that if the network goes split-brain you don't
want each end of the split deciding to take the FSMO role

Also, FSMO roles don't matter that much - new users can still be
created (typically up to another 1500 or more) and schema changes are
vanishingly rare.

So having the FSMO role owner offline isn't a big deal, just bring it
back online when you can.
