I plan to replace data placement mechanism-specific language that you
objected to (but did not replace in your proposed changes) with the generic
terminology we introduce in rfc5666bis.

That's probably closest to your "approach two" but with as little redaction
as I can get away with.

It's not the approach you took in your proposed changes. So as I said, I
will use your proposals as guidance, but probably not merge them wholesale.

I stated some risks to this approach. I'm willing to try it anyway. It's
only spilled electrons, trapped in a change control system, that can be
reverted if we end up not liking them.

Agreed. In any event, I will produce a revision soon, and you can see if
I've corrected the issues you identified.
