That works for your project, but then nobody can include you as a library without conflicts.
I think this is the core to much misunderstandings and arguments around this question. Some people are writing code that only they will run, on a python they've installed, on hardware they control. Others are writing code that has to work on lots of different versions of python, on lots of different hardware, and when being run in all kinds of strange scenarios. These two groups have quite different needs and don't always understand each other and the problems they face.
