Ditto on all points. Also, why does this clause not apply to the cut/copy
events as well? What does "start" mean here? Start in document order e.g. as
opposed to the anchor/base of the selection?

What's the benefit of being different? In general, the closer we can be to
HTML5 DnD, the easier it will be for everyone.

In an ideal world, implementations would support any string type. This would
allow for creating custom clipboard formats as well as common mime types
(e.g. image types). Do most operating systems support setting generic string
types on the clipboard?
