The spec. does not require a GetTable response to be RMPP (only optionally)
so we can easily avoid the RMPP overhead for short responses. 
If you have seen such a requirement please point the exact spec paragraph
that require an RMPP response.
Sending a single mad RMPP response is highly inefficient. (due to the
protocol overhead).
However, the implementation of the RMPP transaction (SAR) can handle single
mad RMPP transactions too.
