Global configuration file merged with project configuration file

I'm trying to use the python language server, pyls-mypy and mypy to asynchronously show me type hints in vim.

This is a bit related to #4542 and #5241.

Immediately I had the problem of Cannot find module named 'a.b.c' which sent me down a rabbit whole trying to figure out what to do. It seems like the answer is --ignore-missing-imports. Since I'm not invoking mypy myself I would like to put this information in a config file. So I put it in ~/.mypy.ini and the error message does not go away. Finally I figured out that setup.cfg is shadowing my configuration file, and yes, putting the [mypy] block in the setup.cfg finally let's me get rid of the warning.

So my question is. What is the proposed solution to get rid of this warning for all my python projects? My preferred solution would be that any project-local configuration file is merged with my personal configuration file (like other tools would do, e.g. git and pylint).

ファイル、テスト、エントリポイントは指定されていません。まず、mypy が ~/.mypy.ini とプロジェクトの setup.cfg をどのように検出して優先順位を付けるかを追跡し、次に関連する issue #4542 と #5241 を確認してください。個人用の設定をプロジェクト間で適用しつつ、プロジェクトローカルの設定を失わないように、明確なマージ動作を定義して実装できれば完了です。
