Exactly!

YES!
I think that one of the biggest problems of SMP is the dependence on 
implementation of parties, even if on most applications security is
not needed and no benefit is visible. Some subset of the Party concept
not implying all the security stuff would have been enough (Sorry, this
is not the S[N]MP discussion !!).
My bet is that we will run for quite a long period in paralel S[N]MP
(to get some of the many advantages it brings) and 'classic' SNMP for
simple applications and back compatibility.
Not retainig Community Strings and IP Addresses in the chasEntityTable
would mean that all existing agents already running in boxes should be
upgraded to support parties. It is not always possible and for sure 
not desirable.
