A... yes I've missed that :)

So does your proposal is that the only support for RDBMS
in zope 2.x should be via ORM like adapter?
Or this should be something additional to current ZRDB, or
you want to change (simplify?) ZRDB to be similiar to
these z3c wrappers (zope transaction handling, connection pooling etc)?

If you say about going into ORM adapters then few things
I wonder about are calling specific (complicated) queries
and/or stored procedures from databases. How does SQLAlchemy
support this? Another thing, what about speed of ORMs in
comparision to traditional queries with ZSQLMethods?
