I assume one for leds one for wdt and finally drop stuff from platform,
and i will go with that assumption for a next round based on your tree

Can you explain why that will be useful? While it is kind of a
separation of concerns and subsystems ... it also kind of all belongs
together and needs to be merged in a rather strict order.
