Comment (by rmccue):

 Replying to [comment:7 spacedmonkey]:
 > The issue here is, that the `REST_REQUEST` is setup until
 `parse_request` filter, this is far late to help for this use case.

 WordPress doesn't know that it's a REST API request until WP's routing is
 done. There's no real way around this; it's simply too early before
 `parse_request` to tell what the request is.

 In the error handler, you could try detecting the `Accept` header, and
 external well-formed requests can send `Accept: application/json`.
 Otherwise, I don't think there's really a solution.
