First of all, Thank You for this blazing fast tool!
I must also say that some of my smaller projects(because it will be easier and faster) will get migrated to ruff pretty soon.

There are however a few big projects which it will not be that easy to fix in one batch.
They even have parts where the rules are not the same.
The good news is, while they are not in a monorepo, ruff's monorepo support and configuration extending by means of additional pyproject.toml and ruff.toml will simplify this.
We will not be using additional pyproject.toml files since, as I mentioned, they are big, but non monorepo, projects.
That leaves us with ruff.toml.
However, I feel like a .ruff.toml would be something that would immediately "say", this is a local configuration file as opposed to something that the project requires to make it work.

Would it be possible to, additionally, check for, and support, .ruff.toml configuration files?
