Well, draft-ietf-json-text-sequence-13 will break this proposition.

It's on the RFC-Editor queue.  We could "fix" the "problem" in AUTH48,
but I've no intention to.

I doubt it's the first RFC that will break your assumption.

Not that it matters.  Suppose all RFCs with ABNF only had a *single*
ABNF module, so that each module could be said to be named rfc1234.abnf.
Now what?  You'd still be missing the machine-readable imports.

We could say that every module exports every rule by default, so we
could get away with not having exports.  But imports are absolutely
necessary in order to validate ABNF modules that import rules from

We already have a mess on our hands.  ABNF needs a module system.  An
ad-hoc module system won't do.
