Thanks Brian,

Yes, as a design of receiving push messages and push message receipt is the
similar and they are both use server pushes, will not be a problem to reuse
already implemented code base to allow this feature for an AS too.

Advantages:

   - More flexible logic for AS (it could choose how it will request
   receipts);
   - Possibility to reduce number of always opened connections to the PS,
   because if a UA may be unavailable most of the time we can not say the same
   about an AS. It's online most of the time, but can request push message
   delivery rarely.

Previously Kit also considered to add this feature:
