Comment (by TimothyBlynJacobs):

 This would definitely be helpful. I'm not sure what the best way to go
 about it is.

 We have `rest_validate_request_from_schema`, but that doesn't have any
 knowledge of the idea of `sanitize_callback` or `validate_callback` and
 I'd be hesitant to add that to what is a generic JSON schema
 validator/sanitizer.

 Perhaps it could live in `rest_validate_request_arg`? Though for similar
 reasons as mentioned in #48818, it'd be much simpler to add it to
 `rest_validate_value_from_schema` since it handles schema traversing.
 Maybe we need a general purpose schema traversing function?
