I believe the question is about dates in protocols rather than dates in RFC document text.

<tp>
A distinction that I think moot.  RFC document text is about protocols!  Besides the References, I see dozens, hundreds of dates in the I-D which I review and for which the format is prescribed.  
 Expires September 26, 2021 
in the running footing would be one example while 
   <CODE BEGINS> file "ietf-i2nsf-ikec@2021-03-18.yang"
must be as laid down by RFC7950 or
       Copyright (c) 2020 IETF Trust and the persons
which must follow the IPR boilerplate or
            <last-updated>2015-10-24T18:02:45+02:00</last-updated>
which must follow RFC6991 and so on.

Tom Petch

For dates in RFCs, we have the <date> element, which in the HTML version is rendered into an HTML <time> element,
so you can reformat the displayed version however you want.

R's,
John
