I can't speak for San Juan. The folks that commented on the PPML were
overwhelmingly in favor of returning NO addresses to IANA. Do I need
to go back and count to prove it? I'm guessing you didn't count before
making your assertion so you don't have the list handy.

Hi Scott,

So you think there's wide support for "no return at least until
there's a ratified global policy for reallocation" while there's less
support for "no return until sometime later than that." So put "no
return until event X" forward to last call and restart discussion on
"no return between event X and event Y" if it's still desired.

I'll have to think about that.

That's where this gets messy. There is a pending ARIN-ratified global
policy for IANA to allocate addresses. The feel is that the other
regions won't ratify it, but they still could at pretty much any time.
Also, the way the text is written, it could serve as the "exception
that proves the rule." In other words, stating "no returns until X"
implicitly means "returns as normal after X" for some external
definition of normal. I'm personally uncomfortable with a policy that
says "returns after X" without laying out exactly what we're willing
to see returned after X.
