risk of downtime anyway because your filesystem root is on a non-RAID

boot disc quickly, you're exposing yourself to a long, slow resync which
will increase your downtime by perhaps days...
That presumes a loss of the boot drive *AND* one or two RAID drives.
That's pretty unlikely, unless something really nasty happens.
I don't think it does - even if none of the RAID drives goes, the system
crashing because of the root drive going AWOL might well leave the
system with the RAID array marked "dirty" because it wasn't shut down
cleanly, which without the bitmap would mean you'd get a full resync
when you rebooted.
Cheers,
John.
