@bmedishe Could you run pre-commit run --all-files in your local setup and fix all the flake8 or any coding standard issues. This will clear static-tests CI failures.

@bmedishe Let's re-run the whole test suite again with the newer changes and attach the passing log here. This way we can identify if there are any regressions early on since we are moving to the newer design.
