some people think X- headers are extremely useful, others think they
were a bad mistake that should be eradicated. maybe we need a
separate RFC about X- fields. I'd hate to see this argument block
progression of 2822 bis.
Ignoring the problem won't make it go away, though. Consciously
removing text is driven by some motivation.
IIRC it was driven by the inability to get agreement on the topic within
the DRUMS WG.
2822 bis will not obsolete 822 in any event - 822 is still a full
Standard, while 2822 bis would only be Draft Standard. As a practical
matter, nothing can really obsolete 822 as long as people still need to
read old mail messages.
