I gathered the impression somewhere, perhaps incorrectly, that the active
flag was a function of the boot block, not the BIOS. We use Grub in the
MBR and don't even have an active flag set in the partition table. The system
still boots.
The active flag is indeed an MBR

Yes, we actually have a separate (smallish) boot partition at the front of
the array. This does reduce the at-risk window substantially. I'll have to
ponder whether it reduces it close enough to negligible to then ignore, but

This is a case where a very small /boot partition is still a very good

I wonder if having the MBR typically outside of the array and the relative
newness of partitioned arrays are related? When I was considering how to
architect the RAID1 layout it seemed like a partitioned array on the
entire disk worked most naturally.
It's one way to do

We are using a RAID1 setup with two SATA disks on x86, using the whole

We will boot from whichever drive the BIOS has first in its boot list
