I disagree.  As I said, the user can drop it in some place where
dropping is a no-op.

And let's not forget that drag-and-drop operation mostly ends in a
drop, not in a cancel.  Canceling should be much rarer than dropping.

I'm not talking about the ones we already support, I'm talking about
the future policies of trying to use alternatives to X.  It was a
response to what you said:

I'm saying that we shouldn't stop looking for reasonably good GUI
environments because we are complacent with X.
