"Will my RAID configuration designed so my system can still boot even if it loses a drive not actually let it still boot if it loses a drive?" is not a question that I think is fair to expect sysadmins to realise they need to ask.

Complete Principle of Least Surprise violation given everything else's (that I'm aware of) RAID1 setups will still boot fine.

Also said monitoring should then notify you of an unexpected reboot and/or a dropped out disk, which you can then remediate in a planned fashion.

If this was a new concept then defaulting all the safety knobs to max would seem pretty reasonable to me, but it's an established concept with established uses and expectations - a server distro's installer should not be defaulting to 'cause an unnecessary outage and require unplanned physical maintenance to remediate it.'
