It should hardly harm anyone.  But what would be a typical scenario for
using it?  C-x b has 'switch-to-buffer-in-dedicated-window', C-x <left>
and friends probably should do the same.  Usually a window is marked as
dedicated to avoid that 'display-buffer' uses it.  In which case it
would likely be better to not mark the window as dedicated in the first
place - e.g. via a (dedicated . nil) entry in `display-buffer-alist'.
