How would that work in practice (concrete example)?
Note: I am not saying it is impossible. I just wanted to make sure that we are making the same set of assumptions.

The implementation partition can register itself (as part of the
static initialization) in some registry.

For example, the implementation partition may include a unit test
(because that's the only way to access the private parts) which
is registered with the test harness.
