It's actually instructive to look how Java solves this:

- The interface is kept upwards compatible, by following rules such as
only new methods/fields etc.

Then to look at how a consumer, Derby, deals with the fact of multiple
versions of the interface:

- Derby only provides and uses the functionality to match the version of
the interface (java.sql.Connection) loaded, determined at runtime.

I'd thought this was a workable direction being proposed about six
thousand message ago, upwards compatible apis and the ability for a
consumer to handle a lower version. Not sure what derailed it.
