Yeah, I agree on HW slave support without interrupts is hardly possible.
But I imagine that controllers differ in which situations they can issue
an interrupt so talking about them for generic code feels strange to me
because $flexiblecontrolerwithvariousirqs doesn't need to send more
events than $bareminimumcontroler.
