Comment (by duanestorey):

 I suspect if you want to just debug and ensure no output happens you can
 just define REST_REQUEST in your code.  It would bypass the same check in
 the debug init.  The actual define later would likely throw an error I
 think, but display errors would be off then anyways.

 Replying to [comment:25 JustinSainton]:
 > @danielbachhuber Would it be unreasonable to make the output of
 `wp_is_json_request` a filterable value? I know I've debugged countless
 issues by noticing errors in JSON output that is often only exposed there.
 Being able to conditionally `add_filter( 'wp_is_json_request',
 '__return_true' )` in some cases would be really valuable. Happy to patch
 if we think this is worth the filter-maintenance tradeoff.
