I'm not sure what you're arguing. JSONFeed is JSON, unless I'm missing something, just JSON that matches a specific schema.
If I'm pulling JSON from any API, I expect it to match a certain schema. If I expected { "time": 10121} from a web API they send me "4", then sure, that's valid JSON, but it doesn't match the schema they promised me in the API.
Something that's JSON should be marked JSON, even if we're expecting it to follow a schema.

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.
This is exactly one of the things that media-types solve. Simply using application/json doesn't tell me (consumer) anything about the semantics of what I'm reading. It only tells me what "parser" to use. If we have a proper media-type, like application/hal+json, I know exactly how to create a client for that type: I need to use a JSON parser _and_ use the vocabulary defined by HAL…

That's what the +json type suffix is for. I wonder how many people in this thread actually have read the mediatype RFCs, because they definitely don't encourage using mediatypes in the way you're describing.
The whole point of mediatypes is to make it possible to distinguish schemas while also potentially describing the format that the schema is in.
