Arduino footprint has many merits : I am evaluating on the nRF52-DK.
However, it could be "nice" for a tight PCB with the io bought out into an easy expansion.
It could be nice to have a smaller Arduino io footprint if possible: the shield is quite big and a tight PCB is definable as small if this is what one wants.
I have to look thru the different versions of a standard Arduino footprint to see if there is enough on a smaller footprint ie tighter PCB
