Motivation for this change

Breaks esphome which subsequently requires platformio, which in turn requires esphome.

Was broken after python3.8 upgraded to 3.8.6 due to this change:

bpo-41314: Changed the release when from future import annotations becomes the default from 4.0 to 3.10 (following a change in PEP 563).

Reported upstream in xZise/flake8-future-import#24.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.
