This is what the RFC says. Only changes that happens "automatically"
is UNASSIGNED -> "SOMETHING ELSE" when new Unicode versions are
released.

Obsoleting an RFC can always change whatever is in the RFC. And this
include (today) the algorithm, the exceptions table etc.
Yes, we have talked about "an expert group" and such things, and long
term yes I absolutely think we will have such a process.
BUT, until then, the only reliable review process we have for changes
is by issuing a new RFC.

Can not happen (yet) as we have no such procedure in place. And if we
have, and require for example a 4 week comment period, what is the
real difference between this and issuing a new RFC?

This is for me out, but mainly because it is today so extremely
hypothetical that I do not see it being possible to discuss.
And, btw, it is _ALWAYS_ easy to make the barrier lower in the future
for changes. Rising the barrier is not easy.
So I am a supporter of (2).
