One option is that people use yang-data as defined in RFC 8040 until
there is a version of YANG that has a proper and complete integrated
solution. (If for example yang-data is used to declare error content
for RPCs, then more extensions are needed or a proper integration into
YANG. Is it really good to introduce augment-yang-data (instead of
making augment work with say 'data' in YANG 1.2)? And then we do
uses-yang-data etc.
