I see that RFC7977 takes a slightly different approach to updating the ABNF:
transport = "tcp" / "ws" / 1*ALPHANUM
The advantage of listing out
transport = "tcp" / "ws" / "dc" / 1*ALPHANUM
would be that the reader sees the full list.
While it might be nice to see the full list, it can't be counted on to
remain the full list. If each update did this, then every draft that
updates the list should formally Update every other document that
updates the list.
The *point* of /= in abnf is that it decouples the particular addition
from all others.
This sort of thing should really have an IANA registry. But often the
expectation is that changes aren't made often enough to justify that.
Lacking that, IMO /= is the preferred way to go.
Just kibitzing,
Paul
