FWIW, I asked IANA whether they have a fixed list of these status terms
and what is their semantics. I got one reply so far saying that they
will discuss it with YANG experts, which of course misses my point. In
YANG, status terms are reasonably well defined, so once we know what they
mean in IANA registries, we can try to map it to YANG.

BTW, there is now a proposal to introduce "preliminary" or
"experimental" status in the next version of YANG:
