The part of the code that handles the boiler-plate stuff (what you call the low-level binding) I see as being  the language-binding framework.  The language binding that we share with customers is written on top of that. We can certainly distribute the framework, and develop it in an open source manner, but I see most of our users simply using the binding.

We can all share the same basic boiler plate code. The binding just adds the specifics for the individual service.  In a very real sense we are all using the  same underlying base  protocol at that point.  Drivers are written to handle the problem of interacting with varying protocols.  If we're all speaking the same protocol, I don't see the need for a driver.  I'd much rather we standardize at the protocol level then to expect service teams to produce compatibility drivers for each service.  Especially when you consider that there are additional benefits to us standardizing at the protocol anyway.

As far as confusion, I don't see confusion around an ORM using a lower-level DB-API/JDBC driver. Providing both is useful. If you provide the ORM and not the driver, that's frustrating.
