OK. However, I do think that deleting windows just like that is too
aggressive and counter-intuitive.

No, dedicated windows in frames that have other windows are too troublesome.
They often surprise the user.

That little ediff window does not need to be dedicated, since nothing else
gets into it unless you try hard :-)
And if this happens then it is easy to recover.

But when you maximize then the little window does not get deleted - it just
gets bigger. It is better to resize a window than to completely delete it.
