I tend to agree with this. Add also the situation that the yocto project
needs to upgrade oe-core to python 3.6 as soon as possible, and to 3.7
soon after, no one has enough time to do this rather non-trivial job,
and I'm beginning to wonder if the best way out is to remove the module
splitting altogether, and write a clean, simple and maintainable python3
recipe from scratch with minimal amount of custom patching and hopefully
no write-only hacks.
