Description
Activity
Support optional paths (eg. not all schemes can provide a
scriptsdirectory)Are there specific examples? What is the usecase for "optional" scheme paths?
PEP 582 would be a good example in a normal environment. See https://discuss.python.org/t/pep-582-python-local-packages-directory/963/391 for some of the discussion regarding it.
WASM would be a good example of a new type of environment where certain paths, like
scriptsorinclude, don't make sense (at the moment at least) 1.Footnotes

Feature or enhancement

sysconfig.get_paths()with something that can accurately describe the current reality.Pitch
The new API should:
