I would personally be inclined to define that whatever spec we come up
with always require #address-cells/#size-cells for any node that can
have either device children or interrupt children, and ban default

When is #size-cells used in the interrupt tree at all?
And given the odd behavior of using an interrupt map in an interrupt
parent that is not the device parent (you're potentially using keys from
different domains that could clash, be a different sizes, etc), if we
make any changes in that regard, I'd forbid interrupt maps in interrupt
controllers with no device children, and thus #address-cells has no
meaning there.
