dired-mouse-drag-files mentions that:

This feature is supported only on X Windows, Haiku, and Nextstep (macOS
or GNUstep).

and mouse-drag-mode-line-buffer:

This option is only supported on X, Haiku and Nextstep (GNUstep or
macOS).

for example.  (elisp)Drag and Drop also features this disclaimer:

   It is also possible to drag content from Emacs to other programs when
   this is supported by the current window-system.
