How about similar features that are in the ns specific files, but should
be generic (if they should be included at all).  

When the ns support was included, I sent a few messages with reviews,
and found quite a few such things.

The ones that  I remember right away are in nsfns.m 

  /* FIXME: Because of the typo below, Qbuffered probably never did
     anything useful, so it might as well be removed. */
  Qbuffered = intern ("bufferd");
  staticpro (&Qbuffered);

??? Whis is this kept around? 

  Qfontsize = intern ("fontsize");
  staticpro (&Qfontsize);

What about this one?

  DEFVAR_LISP ("ns-icon-type-alist", &Vns_icon_type_alist,
               doc: /* Alist of elements (REGEXP . IMAGE) for images of icons 
associated to frames.
If the title of a frame matches REGEXP, then IMAGE.tiff is
selected as the image of the icon representing the frame when it's
miniaturized.  If an element is t, then Emacs tries to select an icon
based on the filetype of the visited file.

The images have to be installed in a folder called English.lproj in the
Emacs folder.  You have to restart Emacs after installing new icons.

Example: Install an icon Gnus.tiff and execute the following code

  (setq ns-icon-type-alist
        (append ns-icon-type-alist
                   . \"Gnus\"))))

When you miniaturize a Group, Summary or Article frame, Gnus.tiff will
be used as the image of the icon representing the frame.  */);
  Vns_icon_type_alist = Fcons (Qt, Qnil);

This definitely looks like it should be generic, or not included at all.

There are a few more in ns-win.el.  Like redefining the standard menu 
structure, but there are more.
