Why is strict mode disallowed in .eslintrc?

[kmoe]

Strict mode is disallowed using the ESLint "never" setting:
https://github.com/gaearon/react-hot-boilerplate/blob/master/.eslintrc#L13

Why is this?

[gaearon]

We're using ES6 modules and they imply use strict anyway by the spec.
Babel's output generates 'use strict' automatically so there's no need to add it manually.

(As far as I know.)

Thanks! Found this which explains it further http://babeljs.io/docs/advanced/transformers/other/strict/

Closing as resolved.
