FIY, I went on to replicate/validate your testing, and I ran on
patches 07 an later:

  isort --check-only --settings-path ./scripts/qapi/.isort.cfg --recursive ./scripts/qapi

With success.

Here on patches 08 an later, I've run:

  flake8 ./scripts/qapi

And starting on patch 24 ("qapi/source.py: add type hint annotations")
it complained about:

  /scripts/qapi/source.py:44:31: F821 undefined name 'T'

Here I ran on patches 09 and later:

  pylint --rcfile=./scripts/qapi/pylintrc ./scripts/qapi/

And all succeeded.

Here I ran on patches 18 and later:

  mypy --config-file=./scripts/qapi/mypy.ini ./scripts/qapi/

And all succeeded.

- Cleber.
