> The linked code does something different.

Right, it addressed other issues encountered in that project:
1 - the need for different paterns for files and directories (http://bugs.python.org/issue16662),
2 - handling import errors at load time (http://bugs.python.org/issue7559 as Robert told me),
3 - changing discovery policy at package level
4 - not importing test files (project specific)

The most blocking issue in that project was that there was no way to address (3). If that's fixed (and (1) as well) with http://bugs.python.org/issue16662, I'm fine with that, I'll be able to build the specifics for that project on top of it.
