The particular case I have in mind is inability for drag sender to
change cursor over other apps windows (in particular Finder windows);
in some cases even if drag sender is foreground app (and in much
more situations when it is a background app). I think the OS idea
behind this is that this is drag receiver who should control cursor
in this case (e.g. changing it to "arrow with plus" for copy
operation) but in case of dragging promised files this doesn't
really make much sense ("to copy/link a non-existent yet file?").
OTOH, the drag sender might choose to provide a different file
content depending upon the current modifiers, and whatnot, so it
would be valuable to allow drag sender to show UI feedback about
what it is going to provide as a drag. I believe the most reasonable
UI feedback in this case is cursor change (or a change of the drag
image itself, which is harder to achieve because it should be
updated during the course of drag as modifiers change).
