would conform to the lower recommended limit. [for reference, the
longest field name that I know of defined in a published RFC is
Delivery-Report-Content-Reported-Recipient-Info (47 characters)
defined in RFC 987.]

LOL, yes, 1*77ftext could define an upper bound.

   obs-optional    =   field-name *WSP ":" unstructured CRLF
This one probably needs an obs-field-name as RFC 733 permitted
space/tab within (but not at the start of, for obvious reasons)
a field-name

No, for the same reasons why there's no  obs-at = *WSP "at" *WSP

it is occasionally necessary to parse old messages

If you occasionally parse RFC 733 messages you will manage that
without syntax in 2822upd.
