What's wrong with doing the following?
(defun message--yank-media-copied-files-handler (_ data)
"Attach files copied/cut from the file manager.
DATA is a string where the first line is the operation to
perform: copy or cut. Rest are file: links. The operation is
always ignored, and the files are only attached."
(let ((files (split-string data "[\0\n\r]" t)))
(dnd-handle-multiple-urls (selected-window)
(cdr files)
(pcase (car files)
(`"copy" 'copy)
(`"cut" 'move)
(_ 'private)))))
It calls mml-dnd-attach-file in message-mode buffer.

Considering that text/uri-list and friends seem to be considered in
others part of the code, is there a function that would parse its
format?

Sure, I can prepare a patch that would copy/rename the file if the user
has copy/cut the file from her file manager. I have code for this
living in my init file.

I believe covering x-special/gnome-copied-files will cover a large
ground of file managers. Obviously, I have no idea how to support file
managers in MacOS or Windows.

See above. I can say that it works with pcmanfm, xfe, and thunar if my
memory serves right.

They essentially serve to perform the same function in most cases, yes.

As in, call the relevant function in dnd-protocol-alist for ^file:///?
This hasn't crossed my mind. I am not opposed to this idea.

Thanks, but copy/paste operations on files should first and foremost be supported in Dired, no? Limiting such support to message-mode seems too narrow and much less useful than it could be, let alone what users would expect.

[ This has been sitting in my drafts folder for many months now. ]
Attached patch adds a yank-media-handler to message-mode to attach files
copied/cut from a file manager. I tested this patch using pcmanfm and
xfe. The regexp for the media-type was chosen after the blogpost [1],
pcmanfm in particular sets the media-type to
x-special/gnome-copied-files.
I strip the null byte in the split-string call in the handler because
pcmanfm adds a null byte at the end of clipboard selection. I don't
know if this is the case with other file managers.
I also cannot find the spec of this clipboard type but [2] and pcmanfm
suggests that the selection is
