My impression reading over the problem a little yesterday was that we could work to provide a common "get me a resource" abstraction in Django that papers over the couple of different ways it has to work, though I haven't looked super far into things that require directory listing (e.g. migrations) rather than direct file access (like templates).
It would be nice to investigate this a bit more, though. If we can get Django compatible, or work with PyOxidiser if we find a reasonable workaround they could implement, it would be great.
