Nit: Removing 3.9 from the matrix means no CI job runs on 3.9 on any OS, but pyproject.toml still has requires-python = ">=3.9" and the Python :: 3.9 classifier. Only ubuntu-latest lacks a 3.9 build; windows-latest and macos-latest can still run it. With nothing testing 3.9, a change that breaks 3.9 at runtime (e.g. stdlib APIs added in 3.10) would merge unnoticed and ship to 3.9 users.

You could keep 3.9 in the matrix and drop only the broken combination:

exclude:
  - os: ubuntu-latest
    python-version: '3.9'

The other option is to raise requires-python to 3.10 and remove the 3.9 classifier.
