How do you synchronize tabs with 'kill-buffer'? If, in a tab, you
retain a link to a killed buffer, that buffer can't be collected as long
as the tab exists. If you just keep the buffer name and the user
creates a new buffer with the same name but for a different file, things
may get confusing.

But that function should be available even for a killed buffer as long
as its object is referenced by a tab.

We can set up a buffer local variable whose value is a function that
'set-window-configuration' would call whenever it finds a window with
that buffer dead. 'set-window-configuration' would then check whether
that function correctly returned a live buffer to show in that window.
If the function succeeded, 'set-window-configuration' could try to
restore the earlier values of window point and start in the window. If
the function failed, 'set-window-configuration' would either delete the
window or display *scratch* in it.

Which is usually set up by the major mode.

In what sense? You have a state you store in a desktop file and restore
from that file. The stored state is immutable. If a file whose buffer
is stored in that state gets modified in between, any positions stored
in the state must be considered invalid.
