Since nc is just a piece of copper attached to the (plastic/ceramic) package, why should drc complain?

A "nc" pin would be like "pas", but gives no error if unconnected.
The documentation of the Renesas TinyH8 states:
"... Do not connect anything to the nc-pins. They might be used as test pins under
certain conditions or used for damping purposes, which you don't know."
I would also like to see a pwr_src pin type which would be the output of the
voltage regulator (or source).  That way the DRC would warn you if you
shorted two power sources together or if you forgot to hook one of your
power input pins to the power plane (and only connected it to a capacitor
instead).
