Naming of these options is confusing. It basically means "still allow to rely on function hoisting, and don't complain about variables unless they are in the same scope".

If .eslintrc.js is a .js would it make sense to put this explanation in a comment next to the added option?

Maybe, but then we almost never change the config so I don't think it's that helpful. Can always blame to a PR if necessary.

This would have caught #13582 (comment).
For now, I had to add suppressions for cyclical Flow references but we can remove this after babel/babel-eslint#584 is merged and released.
I also enabled it for classes. Maybe this is excessive but I figured it doesn't hurt since classes aren't hoisted. I had to reorder two places because of that but it's just copy paste.
