I agree - let's wrap up what we have, and ship it.  We have a number of 
related postponed issues including #cascadedQueries and #countAggregate.  All 
these features would be good so the choice is going with the lesser and 
current v1 with the full expectation that a v2 will be needed, as against 
waiting until all features have been addressed.  I believe we have a design 
that does not exclude the possibility (the syntax being the easier bit).
