Explicit use of 'new available resource' and 'if any' should clarify that ?
If someone wants to mis-read it on purpose, sure that is possible
through out the rfc's - it is after all an engineering document !
imo, it is not ambiguous - nor is it bugprone or problematic.
So I hope the change being affected is not in the name of clarifying it
- iirc, this is the expected behavior from all servers today, ditto for
clients (who use this).
