I understand that.  My questions should perhaps be better put as 

- why should there be a distinct namespace for mapped email addresses?  
I see Joe has provided one reason (which doesn't appear to make sense to me since a large RRType can't be 'hidden' lower down), but my point is that there isn't a reason in the draft.

- why should that distinct namespace have a 1 to 1 link with the RR that it will contain?  
This I think is something quite novel and worth a lot more discussion.
