There is more interest, just not vocal.

May want to look at LVM2 and its ability to use tagging to control enablement of VGs. This way it is not HW dependent.

I believe there is space in md1 superblock for a "cluster/exclusive"
flag, if not the name field could be used
what is missing is an interface between mdadm and cmcld so mdadm can ask
cmcld permission to activate an array with the "cluster/exclusive" flag
set.
