In previous versions of `tox` it made sense to use `envdir` to have multiple test environments share the same directory when they had the same requirements. But since `tox>=4` it no longer makes sense to do this as now `tox` will detect a difference and keep recreating the environment and cause it to be slower than having separate environments. What is happening now is if you run `tox -e black,flake8` it will create the environments. Then run `tox -e black,flake8` again it will again recreate the environments. By removing `envdir` it won't recreate the environments on the second and subsequent runs.
