Thanks for the clarification.

1.
Concerning interoperability, can a MAP-T-only CPE communicate with a MAP-E only DTE? 
AFAIK, the answer is a clear NO. 

2.
Note that, although MAP-E being THE standard, necess , any ISP that provides CPEs to all its customers can deploy any workable solution of its own for the same purpose.
- If the design is right, it can work perfectly.
- Two such solutions are specified in IETF for this (in addition to the standard itself), with different pros and cons (MAP-T and 4rd).
For ISPs whose CPEs may be supplied by customers themselves, interworking between CPEs depends on all of them supporting only THE standard. This becomes supporting ALL THE standards if there are several.

This being said, if the WG consensus becomes that 2 standards are preferred to 1, my point is that it should be done consciously. 
Besides, my personal view remains that, for a given purpose, 1 standard is better than 2.
