"Should be doable" being the operative word. We are not there yet. We need
both new API types (like capabilites) and more settings for existing API
methods(more constraints).This also means either a lot of API extensions in
the future (with new API extension for each new SDP based feature) or
always having SDP as a fallback API surface.  If this is done right we can
just keep constraints and get rid of SDP altogether.
