Comment (by TimothyBlynJacobs):

 I strongly think that we should support `additionalProperties`. It, along
 with `patternProperties` allows for very useful functionality. I
 originally only included `additionalProperties` for the exact reason
 @mnelson4 mentioned, `patternProperties` is something that could easily be
 included later.

 Additionally, if we want to whitelist object keys for use in things like
 meta or settings, then it would be far more preferable to merge the
 setting schema entry with defaults for the object data type that would
 contain `'additionalProperties' => false`. This way custom endpoints would
 work properly that already have `object` validation and you'd have the
 increased "security" for settings or meta.
