That strikes me as an exceedingly bad idea as it will be 
unpredictable to those users that need it. And I do not like
different places for md-RAID 1.x format superblocks one bit.
We should pick one thing, make it otional (but on by default)
and stick with it, so users do know where it is, regardless 
of other parameters.
