Amendment gratefully accepted.

I meant to say explicitly that I hadn't spent nearly enough time
on that text to have any confidence that it was either exactly
correct or not in need or wordsmithing and then sent it too
soon. I am certain it could be improved by wordsmithing and am
not surprised that there were cases I failed to consider.  

The main point I was trying to make is that it really is
possible to parse this issue in a way that separates the read
problems/ risk/ harm from matters of taste and that replaces a
vague "SHOULD" (and "now you get to guess what will be
accepted") into a requirement for explanations and opportunity
for community review. 

A bit more below.

Yes.  I think your correction fixes the problem.

You are right of course.  Better text is welcome if we can agree
on the principle.  It may also be that, if we are going to
permit addresses, some words in the Checklist about preferences
for IPv4, IPv6, or parallel examples would be in order.

I had hoped it would be at least "justify yourself to the
community and then let the IESG make judgments about community
consensus" rather than any of the variations on "let the IESG
reach a decision independent of the community".  The question of
what the IESG should do (or might be expected or required to do)
in the absence of any community consensus is, as you say, a much
larger issue.
