COMMENT:
----------------------------------------------------------------------

In Section 3.2.1:

   Servers are not required to support all values in the "with-defaults"
   query parameter on the operational state datastore.  If a request is
   made using a value that is not supported, then the error handling
   behavior is as described in ([RFC8040], Section 4.8.9).

This seems to be pointless, considering that the server already advertises
support for the "with-defaults" capability. Can you maybe elaborate on which
values are hard to implement (and thus likely not to be implemented)?
