This pattern is already used in
Documentation/devicetree/bindings/gpio/fsl-imx-gpio.yaml. It will
match only children and so far it did not find any other nodes in ARM
and ARM64 dts. I don't expect clashes. Also the question is then - if
one adds a child of GPIO expander named "foobar-hog" and it is not a
GPIO hog, then what is it?
