that's exactly what I want.

I do not and will not use the customization ui.
I want my settings where I can read and modify them.

it produces a lot of separate entries like
 (((name . "*acl-listener*"))
  fun-with-args
  (fun-with-args special-display-popup-frame #1#))
 (((name . "*scheme*"))
  fun-with-args
  (fun-with-args special-display-popup-frame #1#))
 (((name . "*allegro*"))
  fun-with-args
  (fun-with-args special-display-popup-frame #1#))
 (((name . "*cmu*"))
  fun-with-args
  (fun-with-args special-display-popup-frame #1#))

I think it would be better to group them together like I do above.

also, it converts same-window-buffer-names into 
 (((name . "*Diff*")) reuse-window (reuse-window same))
how is this different from
 (((regexp . ".*")) reuse-window (reuse-window nil same 0))
  
also, special-display-popup-frame is marked as obsolete, so
display-buffer-alist-set should not be producing it.

also, how is
 (.... fun-with-args (fun-with-args special-display-popup-frame #1#))
different from
 (.... pop-up-frame (pop-up-frame-alist ....))
