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...
