Indeed, it's puzzling, because working groups and technical areas vary
with regard to what's important for that work or technical area.  RFC
6410 re-defines the "Standards Track" into two levels (down from
three): Proposed Standard and Internet Standard.  It's the latter for
which we need multiple deployed implementations to give evidence of
both utility and interoperability.  For Proposed Standard, there is no
requirement for that -- no requirement, in fact, for any
implementations at all.  It's a proposal.

That said, there's not much use in a proposed standard that no one
wants to implement, and we've found that the best proposals are those
that are developed in parallel with implementations, having the
development of the specification and the code feed back on each other,
with interoperability testing along the way.

See RFC 6982 for one proposal for documenting implementations as the
draft is developing.  I strongly support that mechanism.

Exactly.  (1) is, of course, necessary for any work to proceed in any
working group.  While (2) is not strictly necessary according to RFCs
2026 and 6410, it's reasonable for a working group (and/or an Area
Director) to push for that in order to demonstrate that people are
sufficiently interested in the work to move it toward implementation
and deployment, and to improve the specification as I mentioned above,
by finding the bugs, gaps, and implementation problems early, before
the spec is published.

I would not want to see artificial road blocks being put up against
anyone's proposal.  At the same time, in order to proceed with any
proposal there do need to be enough people interested in working on it
to get it done and to make it a useful product of the working group.
