So you want a routine to set the sizes of all children of a window?
What would you want to pass to that routine? A list?

The new size of one window. Applying the new sizes of all windows is
done transactionally, all at once (or none at all if there's a failure).

And who does delete the window _and_ resize the remaining ones?

It would get us into hell's kitchen to just swap some pointers. The
more so because you want redisplay to happen in between. What do you
think window-configurations have been invented for?

Because at the time the window-manager shrinks my Emacs frame I usually
want to work with some other application.

There might be no redisplay in between.

In many applications (Thunderbird is one of them) I can make subwindows
disappear completely by dragging one of their borders and make them
reappear later by dragging on the border where they disappeared.
