What makes sense is not to have that by default and let users switch
windows as they wish. If I have horizontally split windows:

1
--
2
--
minibuffer

and I change window 1 to 4, upon completing minibuffer window 1
becomes 4. I cannot see why. I need to consult 2-3 buffers while using
minibuffer.

Why is that default there?
