We'd still have to decide whether and how to honor buffer-local values
of variables like `window-min-height' or `split-height-threshold'.

When the window configuration changes Emacs often tries to preserve
proportionally the size of non-fixed size windows as faithfully as
possible. How would `balance-windows-area' help here? Doesn't it try
to give all windows the same size? The doc-string isn't of much help
here :-(
