 There is a related Gutenberg ticket,

 Handling `null` is probably the safest way to go. It is hard to see a
 reason why someone would expect the `string` `"null"` to appear in the
 response body when using the `null` type in PHP and as such is least
 likely to cause a BC break.

 We could also consider adding a `_doing_it_wrong` if a response body is
 sent with a `204` response code.
