Where exactly do you raw the line here?  Do we have to support RAID /

Well, what about the case where /boot resides - say - on a multi-drive
RAID1 array?

Is my understanding correct that boot times are only a secondary
concern to you, if any?

Please look into Tom's proposal to got the SPL / Falcon mode way. I
fully agre with him there.
