Please suggest better documentation then.

The text is from the Elisp manual and I hinted at it because I thought
there was a frame parameter for controlling dedicatedness.  I was wrong
- there is no such parameter.  You rather have to set the variable
‘display-buffer-mark-dedicated’ to non-nil or bind it around the
‘display-buffer’ call.  That's very ugly.  I think we should provide an
alist entry like the `reusable-frames' one to control the dedicateness
of the window used.
