Not really, but your answer makes me realize that my solution above is
not enough.

And I actually have a better solution in winsize.el, but it is quite a
bit more elaborate and probably not what we want.

Instead I believe we want a variant of enlarge-window that is not
allowed to delete-windows. Building on that we can make a more simple
solution.
