That's not the way to move forward on this. It will break a lot of projects.

Hey Marcelo,
Please suggest the correct way, I want to contribute

[Kludex]

The thing is, if we merge this, there will be a lot of people complaining because I broke everybody's logging setup.

We need a way to move towards this idea in a way that doesn't break people's code. I think the idea is to move towards v1, and then on v2 change this.

FYI: I haven't removed the existing logger "uvicorn.error" code diff,
I've added a new logger "uvicorn.log" and used it,
Do you still think it will break?
