Thanks for the clarification.
Maybe. But MIME sort of blurs the lines between the identity definitions
and the encodings. And you sort of blurred the lines by only talking
about MIME encoding and then using that to say that "extending the line
length limits" was incorrect.
Until MIME was defined, the notion of binary email was totally
non-standard and there was no way of expressing such email. MIME gave us
those tools, and subsequently *did* extend the limits.
Yes, "binary" is in the identity domain. But it does indeed extend the
limits and it was MIME that did it.

I suggest changing the wording "extend this specification" to be
"shorten or extend this line length limitation".
That works for part of the problem, although it only applies to the
generation (not parsing) part of the 2822 grammars, contrary to the
description of section 2 provided in section 1.2.3 (the 2822upd-04
parse grammar contains neither of the restrictions specified in
draft section 2.3). And as noted above, there are relevant RFCs
and errata not mentioned in the draft.
Okay.
However, I don't think it's necessary to mention all potentially
relevant RFCs and errata. This particular paragraph was using the MIME
RFCs as examples.
