I like the consistency this brings. My only feedback is that in the other
examples I found (common.yaml and leds-gpio.yaml), the children count off
from 0 (e.g. led-0) instead of 1 as your series appears to.
That's not a huge deal; it simply seems more consistent to count from the
first index allowed by the regex (0). The patch is still fine, and so:
