 From https://github.com/WP-API/WP-API/pull/1281#issuecomment-111337989:

 > We're going to tone this one down a bit. Instead of requiring all
 arguments to be registered, we're going to require all registered
 arguments to have either a validation callback or a sanitisation callback
 (or both!). This stops people from accidentally misspelling
 validate_callback/sanitize_callback, but won't stop them from accessing
 other unregistered arguments.

 Currently, developers can register arguments without any default form of
 validation or sanitization.
