Comment 5 for bug 1876370

pyvevnv.cfg is being filtered out, so far seems like the root cause of the issue (https://github.com/python/cpython/blob/8510f430781118d9b603c3a2f06945d6ebc5fe42/Lib/site.py)

This file is required as the v2 python plugin used in core20 behaves more like a virtual environment. There may be legitimate cases to filter this out, so my suggestion is for the plugin V2 API to be extended to have a "get_highly_recommended_files_not_to_filter_out" call (not with that name) to be able to surface this on stage and prime filtering as a warning.
