This is equivalent to providing dummy pincontrollers as was on my
TODO for a while admittedly.

For consistency with regulators it would maybe be better to have
optional dummy pin controllers but after thinking a bit about it
I think this is more helpful, so I applied it anyway.

However I would invite more opinions...
