Stop right here. fax is not a module, it is a package. FooBaaBaz is a
module. So if you want fax.FooBaaBaz.g_magicNameFoo, you need to
__import__("fax.FooBaaBaz"), not __import__("fax").
package = hierarchy of modules (directories with __init__.py inside)
module = leafs in the hierarchy of modules (.py files)
The result of that __import__ is indeed the top-level package "fax"
(or actually, in the LibreOffice code, the top-level package
"wizard"). From that you get the module FooBaaBaz, and from *that* you
get g_magicNameFoo.
I hacked pythonloader.py "in-place" so that it loads the fax wizard
correctly; that should give you the idea of how to fix it correctly
for the general case. I expect calling code chopped off the last
component that I add back manually, it should not do that.
Here's the diff:

It is not flattened.

Yeah, doing that change on top of my existing services.rdb got me
started.
