The server MAY implement obsoleted nodes or MAY NOT. This may or may 
not  is not good enough as a contract for the management client.  My 
problem is that the current solution is just not good enough. IMHO we 
need to change it.

Even after semver you can still obsolete the old stuff and provide the 
new stuff with a new name, although that might not be the common 
practice.  Which is a good thing, as I believe it is sometimes better to 
correct existing definitions then to replace them.
