I do something similar to Thomas. (Also MIT licensed). I like objects. I like
type hints.
Each plugin needs to have check and purpose functions and accepts either
PluginSpec (by default) or AddonSpec if it defines addon = True
This requires a single-level plugin directory with no extra files in it (unless
they start with _, like __init__.py)
And I should use os.path.splitext but I forget what’s it called and find it
easier just to split.
