that's virtually in every tool/daemon. I don't see this as a real layer. 
Just a simple helper to do it right everywhere.

The only partial advantage you have, as i documented and wrote to 
cluster-devel, is that if you are connected to cman and cman_is_active, 
you are guaranteed 99.9% to connected to ccs without problems (only 
reason for rejection would be lack of resources on the machine, but at 
that point you have more serious issues to worry about).
