What would seem useful to me is VGA output. Just a 3-bit (8 colour) text display to keep I/O and memory requirements low, should be good enough for debugging, diagnostic and status display. With the right choice of font you can present larger characters and it could reasonably replicate plant and process displays.
You could provide holes to save on the cost of a D15-connector, leave it to the user to add, or just take it to a row of 0.1" pads.
