True in that Thiago's referenced post said 32-255 range.

However, not quite true in that Thiago's prior post 
<mid:10096467.9kdZcmANtY@tjmaciei-mobl1> says:

"Could we get 32-255 to be slightly stricter but not to the level of 
standards
action? I was thinking of publication of a draft to this WG and allow 
for a 2-
week comment period. This could both spur ideas from other passive watchers
and ensure high quality of the ones that do get published."

"do get published" = draft turns into an RFC. But it can be independent 
stream. That is congruent with RFC Required.

The other problem is that we are already half exhausted out of the 
32-255 range. It's going to go entirely pretty soon.

I believe that 32-255 should have a higher level of review than 
256-<some fraction less than 65535>. We need to de-stigmatize the 
256-65535 range. It is perfectly acceptable for widely deployed 
protocols--even for IETF Standards-track protocols. But I think right 
now everybody is trying to go for 32-255 and it's just not sustainable.

Oh, also Carsten's post 
<mid:[e-mail]> said "I like that" 
for RFC Required to 255. :-)

In <mid:045601d543ac$b79f3d40$26ddb7c0$@augustcellars.com> Jim proposed 
Specification Required with a consideration: "Reviewers should be 
reluctant to assign code points in the 24-255 range to specifications 
that are not RFC documents."

However, with regard to the present tag 42 problem, Jim proposed that we 
encourage early IANA allocation. The point is that early IANA allocation 
+ RFC Required will alleviate the problem, and will also permit higher 
analysis + early allocation in the 256-65535 range.

So I think there was not consensus on the mailing list at the time but 
the trend was going towards segregating the spaces into progressively 
higher levels of review.
