Python is moving to have a lazy loader as part of the standard library. I mean, it's there already, at https://docs.python.org/3/library/importlib.html#importlib.u... , but not clearly easy to use, and with a big warning label against using it.

The issue at https://bugs.python.org/issue32192 says the plan is to start with an easier to use system as a PyPI package.
