This is unlikely to fly for RHEL-based distros as pcs is the only
officially supported way of interacting with a pacemaker cluster.
I think in the short-term it makes sense to somehow have both mechanisms
in place (is this even possible?) and then once 'pcs' hits the stable
debian-derived distros to invest in that direction.

I am definitely interested in this work. I will start looking at the
pcs provider changes and hopefully bring some feedback. If you do
have any questions on the pacemaker side of things, please do reach
