I'd call anything that relies on a specific file system layout to be
internals. We only make guarantees on the semantics of the Python
import system, not how packages and modules are stitched together in
distributions and end up on the file system.

I agree with that. I thought the call to software home was being made
inside ZMySQLDA and not in Zope 2 code.
