Warnings about strings in eslintrc

The ESLint documentation suggests that the strings “error”, “warn”, and “off” can be used instead of the integer values, for example semi: ["error", "always"].

Currently, VSCode brings up a warning when using this syntax:

Incorrect type. Expected one of integer, array

OK. Here is what I found out using eslint version 2.10.2 (the latest)

• using “off”, “warning”, “error” is not allowed of a rules if this is the primary property

        "semi": "warning"

doing so result in the following error when executing eslint from the command line:

P:\mseng\VSCode\Playgrounds\linters\.eslintrc.json:
        Configuration for rule "semi" is invalid:
        Severity should be one of the following: 0 = off, 1 = warn, 2 = error (you passed '"warning"').

Error: P:\mseng\VSCode\Playgrounds\linters\.eslintrc.json:
        Configuration for rule "semi" is invalid:
        Severity should be one of the following: 0 = off, 1 = warn, 2 = error (you passed '"warning"').

Using this inside an array works as expected and Code doesn’t print any warning/error.

        "semi": [
            "error",
            "always"
        ]

I will close the issue since there is nothing VS Code can do about this.
