Documentation conflicts with object-property-newline setting?

It seems like the documentation consistently promotes having a new line for each item in multiline lists, whether it be in a [function invocation](https://github.com/airbnb/javascript#functions--signature-invocation-indentation) or in [an array](https://github.com/airbnb/javascript#arrays--bracket-newline) (both of which mention bad examples of not having each item on a new line).

And even the [object examples](https://github.com/airbnb/javascript#objects--quoted-props) (although not referring to this specific rule) seem to favor this approach.

With that said, what is the reasoning behind [allowing object properties to all appear on the same line](https://github.com/airbnb/javascript/blob/17e0454672f784772c5f5ab052523a93229d9adf/packages/eslint-config-airbnb-base/rules/style.js#L406)?

It would seem more consistent to remove that option for `object-property-newline`. But at the very least, the reasoning and/or use case should probably be documented.

Start with packages/eslint-config-airbnb-base/rules/style.js at the object-property-newline configuration, then compare its option with the linked functions, arrays, and object sections of the style guide. Determine whether the guide should explain the option or whether the configuration should be made consistent, and document the chosen behavior and rationale.
