+1 supporting adoption of this document.
Also interested to contribute to the effort.
+1 on Mcr/Carstens suggestion to be fast & furios (don't drag this out for
long).
Wrt. to APIs and IETF: I expect that we may need to refine terminology
to pass IESG review, such as maybe requiring us to more often emphasize how
this is an "abstract API", or definition of "northbound service features"
or the like (even in the title).
[ Any time we use the term "API" without further
atribute, there are folks wanting to misinterpret it as a "concrete API"
(for specific programming language). Which is what the IETF does not like
(and has no real expertise in), and which the draft also not attempts to
specify. ]
