Yes, that's the ultimate goal.

However, I think we should be very careful while updating the ABNF. 
Therefore it would be good if we can get it into a state where an RFC822 
parser can process it first (that will allow us to parse and normalize 
the grammar, enabling proper change tracking).

Understood.
