Hi Alberto, and thank you for your feedback!

Fernando, Fred, Xing and I met on Friday morning to discuss 6145bis.
This exact issue came up. Suffice it to say that new text that
approaches the problem in much the same way you suggested is already in
the works, so please wait for -01 and let us know if that addresses
your concern in a satisfactory manner.
