This would be nice if everyone used that. When I looked at the source code for mayan-edms, they weren't using that.

Apache airflow? Doesn't use it. Jupyterhub? Doesn't use it.

I was happy to see projects like Zulip using this, but if it's optional then I can't rely on people actually using it. It's the same thing with ruby/sorbet.

That’s shifting the goalposts a bit. You can use optional typing in your project as it’s scales, and there are plenty of projects that have been stable for what they do through other testing. Pick dependencies carefully and use typing as needed

I'd say typing is even more important when you are using other people's code with your code. It's also a huge productivity boost too when the relevant methods and types are available to you, the editor almost writes the code itself!

The projects that don't use it probably need to maintain compatibility with Python 2, for whatever reason. I expect that more and more codebases will be at least somewhat typed as Python 2 is deprecated everywhere.
