We do that all the time.  For example:

  (display-graphic-p &optional DISPLAY)

  Return non-nil if DISPLAY is a graphic display.
  [...]
  DISPLAY can be a display name, a frame, or nil (meaning the selected
  frame's display).

In polymorphic interfaces, the alternative is to say
DISPLAY-OR-FRAME-OR-... which is too tedious.
