The change was not inserted into the document in February of 2016.  Be that
as it may, my point is that this particular aspect of the discussion is out
of scope: if there was a process failure, appeal is your option.   I agree
that it's not a practical option.

So, independent of that, if you think that the current documented consensus
is a *problem, *then you are absolutely right to want to do a new document.
  If that's what you want, you need to do (at least) two things:

1. Explain, in a way that actually makes sense, what it is that the
document says that is wrong, and why it is wrong.   You haven't done that.

2. Explain what it should say instead.   I would argue that your
explanation either has to say "privacy isn't that important after all" or
else address the privacy issue in a way that is equally satisfactory.  I
don't see any way to do that with IA_NA.   IA_NA by definition puts the
whole privacy thing off on the DHCP server, which may or may not do the
right thing.   The client has no agency.   Using IA_PD or prefix delegation
are both clearly superior solutions to the problem.
