Few parts of the spec are perfectly implemented anywhere today, indeed.
That's what it'll take years to get to -- that's where the "2022" estimate
comes from, in fact -- I doubt we'll have two perfect implementations

I don't see why copy and paste is different than drag and drop here. In
both cases, you would want to push a promise into the dataTransfer (or its

Yes, I think this is a worthwhile addition to the API -- once the
implementations are closer to what the spec says.
