@mr-cal I pulled down this change and tried to run the local tests described in HACKING.md. I frequently seeing this error:

ROOT: provision> .tox/.tox/bin/python -m tox run -e py310-unit
ROOT: HandledError| provided environments not found in configuration file:
py310-unit

[stephensp]

I have tested these changes and the new container fixes the previous failures we were seeing when running local tests.

Store spread test failure is unrelated (#4411)
