"DEPRECIATED" is an IANA attribute state I am not familiar with, I
assume you mean "deprecated"? :)

That is not how the process works. An implementor should not be rewarded
with the possibility of laziness after they squat on a codepoint.
"Laziness" being that they don't have to renumber, and that they didnt
have to go through the normal process to obtain the codepoint.

I argue that we cannot tolerate: "I'll just take this one, IANA will
give it to me anyway later on if the product becomes popular"

Also, the 'deprecate' draft (if published) would be "updated", not moved
to historic. Only when all six proposed squatted points are returned to
the "unassigned" pool the document can be declared historic.

No, the main point is to prevent another deployment issue like Large BGP
Communities suffered. Large BGP Communities has been resolved now (after
considerable effort I might add).

This document protects innocent bystanders from being assigned
undeployable tainted codepoints.

Kind regards,
