I am linting my project from two places. Firstly, I run eslint in a shell as part of the CI process. This will have a current working directory that is the location of the .eslintrc file.

I also run the ESLint plugin in VS Code. The current working directory for this is the project root, which is not the same location.

If I set the project setting to be tsconfig.json, and tsconfigRootDir to be . then I can run eslint from the shell. And if I set tsconfigRootDir to be path/to/my/subproject then I can use the VS code plugin. But there is no possible combination of options that let's both work.

Furthermore, tsconfigRootDir seems to be entirely redundant anyway, because there is no combination of project and tsconfigRootDir that can't be just concatenated into the project field, like { "project": "path/to/my/subproject/tsconfig.json" }
