I was taling about the "usage" side.  That is, whatever is involved in
making the think actually useful to... users.  The track record of
achieving real utility for new RR types has been very slow indeed.

I'm guessing that this is the distinction between a new RR type,
versus a new use of an existing RR.  Of course, any new definition of
an SRV must overcome the user-side adoption issues (in this case,
administration by name owners and use by the rest of the dns client
world.

Well, at a minimum, your observation makes clear that a) having the
dns people change their administration model is one of the various
barriers to adoption that must be anticipated, and b) frequent or
massive changes are not likely to be feasible anytime soon.

There is a difference between adding a new record, here and there,
occasionally, versus lots of new records and/or lot of changes over
time.

My view is that this is the sort of thing that leads to failure of a new
proposal. It establishes problematic dependences for
otherwise-independent efforts.

It's not that your statements are incorrect, it is that they involve
unknown amounts of additional delay, and that sometimes the delay
turns out to be infinite.  For example, the entire world was promised
that we would all be using X.400.  Anyone who built that into their
business model had a problem.

In other words, predicting the future of independent activities is
always a dangerous enterprise.
