Very little is actually changed :-)
These days cman is mostly just a small corosync plugin.

I'm not sure if this was the case back when we ported Pacemaker to
corosync, but it would have simplified a lot if we'd sucked in that
little plugin instead of writing our own.

No, we're only using cman for its quorum and membership information.
And the only reason for doing that is so that everything is getting it
from the same source (and the "native" pcmk variants aren't widely
available).

Everything else is unchanged.
