if you write a draft and have running example code, you are accused to

The Postfix code for DANE in SMTP was developed in parallel with the early
drafts of RFC767[12]. I don't recall any "rubber stamp" objections. Perhaps
that was an exception, but at least that objection is not universal.
Work on the Postfix code began in Mar/2013 and on the new drafts in May/2013.
Stable code in Postfix 2.11 was released in Jan/2014, and the RFCs were
finally
published in Oct/2015.
Going way back, there were at least three implementations, two by two of the
specification coauthors, developed in parallel with the MIME specification.
Since then I've always tried to code in parallel with the specifications I'm
involved with.
None of this was in any way secret - in fact I've often stated that my position
on such-and-such was the result of implementation experience - and I don't
recall ever getting any flak for it.
Hopefully this experience isn't unique to email protocols.
