The same reasoning can apply to your backend daemon, so when using
the GPIO aggregator, you can just control a full gpiochip, without
having to implement access control on individual GPIO lines.

I tried to look at it and it surely looks very temping and may fit
well and reduce size of my backend :)

I am now wondering how interrupts can be made to work here. Do you
have anything in mind for that ?

GPIO sysfs already supports interrupts, just that you need to register
irq for the specific GPIO pins inside the aggregator ?
