Yes, this is a good solution for gdb-mi.

As for the desktop, we need to find a solution what to show in a saved
window when the file was deleted before restoring the saved file buffer.

Or maybe this problem is not specific to the desktop: even during the
same session, when a buffer (saved in the window configuration) was killed,
then restoring this window configuration just removes the window where
this buffer was before.  Often this has surprising effect.

What is the alternative?  Maybe to show an empty buffer in its previous
window with text like “killed buffer was here” and a button to restore it:
in case of file buffers it could call 'find-file'.
