13898	Make ACF more robust, and document it better	Wim Leers		"https://www.drupal.org/node/2585173 and https://www.drupal.org/node/2598070 show quite severe DX (Developer Experience) problems with CKEditor's ACF (`allowedContent` + `requiredContent`).

Some things are subtly broken (#13886).

Some things that you'd reasonably expect to accept data in the same format in fact do not accept data in said format (see https://www.drupal.org/node/2585173#comment-10456981: `requiredContent` does not accept the object format, unlike `allowedContent`).

Making it more robust by throwing exceptions if the provided data does not comply with one of the known formats would improve DX significantly.
