I don't understand what does this "keep original window intent" mean.
Please explain.  I want to understand how it is different from other
modes that display a buffer in another window, such as e.g.
after `C-x C-b' (list-buffers) typing `C-o' displays the buffer
in another window, or e.g. typing `C-o' in the Dired buffer
opens it in another window, and many other cases.

Display actions have been in Emacs for a long time customizable
by `display-buffer-alist', so if you need some specific logic,
it's easy to implement the corresponding display action
that can be overridden by the users.
