 > The `/wp-json/` path is filterable, which would happen much later in the
 stack, so I think inspecting `Content-Type` is more reliable and precise.

 Your talking about the response header? Wouldn't that only get set once WP
 understands that it's a REST response, which is basically too late (ie
 after the debug init)?  I would think as soon as a debug statement was
 echoed the web server would output all response headers, which then
 wouldn't work for detection. Or am I misunderstanding?
