The same problem exists with all other uses of window-configuration.
One example: the desktop saves all windows with their buffers.
If a file was deleted before restoring the desktop,
or a buffer saved to the desktop was non-persistent,
then the desktop just deletes the window where the old buffer
was displayed, or replaces the old buffer in the window
with some other random buffer.  This loses the window layout
carefully created by the user.

So instead of replacing the name of the killed buffer
in the tab name with some other random buffer name,
a more proper solution is to keep some placeholder
in the window where the buffer was displayed.
This is a bigger task, so a new request could be created
to implement it.
