No, this is incorrect. The browser can support keyboard-based drag and drop.
There's nothing in HTML5 that implies the user agent has to have mouse support
to do drag and drop. It doesn't even require a visual media UA -- you could
implement drag and drop in a speech browser, and still be compliant per the
HTML5 spec.

I have no idea what you mean here. setDragImage() is available on the
'dragstart' event, which is a DragEvent, not a MouseEvent. It fires
irrespective of the input device used to trigger drag and drop. That's entirely
up to the UA. It could be triggered by foot pedal, that would be just as
spec-compliant.

The drag and drop feature is media- and device- independent.

There is. All the events in the drag and drop model work like this.

Nowhere in the the spec does it show how this functionality is exposed to the
mouse user either. The spec is input-device agnostic. It allows the user agent
to implement the interface however it likes.
