I feel the same.

I am very much back and forth on the subject.

Simplicity of use vs modelling the system as it actually works.

Back and forth.

I honestly have just a very vague idea about this.

I don't know if Marc Z as irqchip maintainer has some idea
on how to model inverters on irq lines or if he's seen some
solutions to it out there.
