I don’t think we have any other or better alternative then getting rid of this AD0001

Tagging @gewarren for any needed doc updates.

@gewarren For more context, there is still a possible breaking change, but it's very very minor and a "silent" one.

If .editorconfig was passed as an additional file, and it's not in the project's directory (or an ancestor directory), then it won't be used. But this is very uncommon, I think.
