I do stuff like that too.   I always like to use an I2C connected LCD
display while developing code on any micro processor project.  I might take
the actual LCD off at the end but I always leave the signal pins in place.
I might need to debug the device again some time and then I can find
another display.  I see a lot of this in commercial products, for example a
USB connection on the back of my TV, only for diagnostic use.

Same with "heartbeat" LEDs, they let you know the device is cycling through
its main pressing loop and not hung.
