Then this should be an option instead of a plain variable.

We have 'display-buffer-alist' for quite some time now.  So please
consider making this an action alist entry.  That way a user can
decide whether all buffers displayed by 'display-buffer' should be
dedicated or only certain ones and which 'dedicated' value they should
get.

OK.  I think we can get rid of the DEDICATED argument then.
