Are you sure this is not allowed? My local UA-MTA (dtmail-sendmail)
certainly allows if, and sendmail.cf automatically cleans it up before
letting it be seen in the outside world.
Do not confuse the myriad illegal formats allowed and fixed up by sendmail
(or most any other MTA for that matter) with
The incomplete form never gets seen on any "wire". So is any standard
violated in that case?
There's considerable value in having a standardized submission protocol in
