It's easy to convince me ...

If we did that, we'd probably get rid of the behavior you started this
thread with.  But the current semantics is "when we have to replace a
buffer in a window with another one, try taking the buffer that has been
shown in that window before the present one".  I'm not quite sure how to
describe what you want to do instead.
