Yes, and everything is application/octet-stream, so why have mime types? Because it helps with tooling, discovery, and content negotiation. It is a hint for the poor soul who inherits some undocumented ruby soup calling your endpoint.

Being as specific as possible with mine types is a convention for a reason. Please don't break it unless you have an explicit reason to.
