I am bit surprised that the principle of the reason haeder in general and reason headers in requests are discussed. I thought this has been agreeed in RFC 3326.
In my understnding the intention of the draft is to allow reason headers in responses.

My intension  is to avoid your shown ABNF for new INVITE header fields.
Instead we want to use the ABNF defined within RFC3326 as follows:

 Reason            =  "Reason" HCOLON reason-value *(COMMA reason-value)
 reason-value      =  protocol *(SEMI reason-params)
 protocol          =  "SIP" / "Q.850" / token
 reason-params     =  protocol-cause / reason-text
                      / reason-extension
 protocol-cause    =  "cause" EQUAL cause
 cause             =  1*DIGIT
 reason-text       =  "text" EQUAL quoted-string
 reason-extension  =  generic-param

The only one missing is to allow this header within Responses.

To clarify the point I was trying to make in the meeting today -- if we've decided to go down this path, I'll save you the trouble of creating the new ABNF for the new INVITE header fields. Here's what they look like:

Nature-Of-Connection-Indicators          = "Nature-Of-Connection-Indicators"

Perhaps we can refine some the the quoted strings with tokens, but I think this is a good start.
