ietf-nntp AUTHINFO SASL protocol choices

No, you are jumping to conclusions.

The ideal is to attempt to modularize extensions to minimize the impact on
other commands. That does not mean that you can't impact other commands, but
that you should have a very compelling reason to do so. Changing the length
of a command buffer so SASL works is not a compelling reason to do it for
all commands since only the SASL extension really needs to have the length
adjusted.

If there are two extensions that have some effect on the same command, then
it is the responsibility of those that create the second extension to define
how such interactions might occur as part of the process of defining that
second extension. To ignore this is to create chaos and that's one of the
things we are trying to minimize here.

It may be that such things need to be clarified in the base draft so that
folks will not be confused about this.

Interesting.

This directly implies that we intend extensions to introduce new commands,
never add aditional parameters to existing commands.  Is that correct?

(Otherwise two extensions which affect the same command can cause all
sorts of weird interactions.  I can go into more detail if it's not
clear what I mean here.)
