Yes, this seems to be only of historic value.

Do the individual subtypes that this draft is registering have UTIs, or 
should they have them? If yes, then having this field is definitely 
valuable.

I'd propose you also ask for advice on
https://github.com/svgeesus/ietf-justfont/issues/24 and
https://github.com/svgeesus/ietf-justfont/issues/23
here on this list, because I think that's where the chance of getting 
some valuable input is highest.

Regards,   Martin.
