Maybe I'm misunderstanding the proposal but..

This seems like such a niche issue I think it isn't ever going to get
traction.  Having a common pool of hot spares doesn't buy you much if
all the different volume managers were to experience a failure -- in
that case the sharing actively works against you (if you've only
accomodated for say 1 of the 3 different volume managers failing at any
one time; but if you have provisioned for worst case of all solutions
failing then what was the point of the exercise?).
