I think that the discussion about whether one could or should completely
replace ZODB with SQL is less important than providing good connections
to SQL while other things are done with ZODB. (After all -- python
provides functions and classes, but it never says: either develop only
with one or the other!)

In my application it is perfectly clear (for the moment at least:)) what
things are part of the UI/application interface (ZODB) and what things
are data that needs ACID transactions, write-ahead logging and ODBC

In general, many people who use relational databases do so for a good
reason. I once worked on a project where we had to rip out ObjectStore
after much frustration delay and expense for scalability reasons.

What I'm having to write myself in this project, would have liked to
have had, and perhaps wouldn't mind contributing to ZPL versions, are
containers that allow one to open a window on the SQL world rather

As it turns out, I've already done my object marshalling because our
system has a Twisted/spread interface as well, so I didn't need SQL
specific object marshalling (though a way of mapping annotations to DB
would have been nice, as I hadn't included that in DB design). Rather, I
just need containers that know that their contents live "out there
somewhere" in a transaction based system that is itself responsible for
object keys.
