What is the point of putting LEDS in the sockets?

Just give me 4 leds in the middle of each section, showing positive/negative voltage from the input.
that would

A: Serve a useful logical function
B: Not be a complete waste of time and solder.
C: Look cooler then a bunch of static invisible orange lights you'll never see anyway.

Otherwise a high quality mult, let down by stupid design choices.
