I don't think so. The weston has a clipboard object which will cache the 
contents of selection and create a data source internally. If 
set_selection set a NULL data source, the clipboard will call 
wl_seat_set_selection() to take over the data source ownership and 
notify the client with selection and offer. See 
clipboard.c::clipboard_set_selection().

But, I should say "weston has no way to do that" instead of wayland.

I think you mean NULL data offer.
