Is there a way to type the output json response?

[NagabhushanS]

Currently, the RequestHandler does not have a generic type for the output json response. With the request handlers now returning a Response rather than a json object, is there a way to type the output response (since Response by itself doesn't have generic type params)?
For example, something like

interface OutputJsonResponseType {
    ...
}

export const GET: RequestHandler<OutputJsonResponseType> = ...
