Hi Christian, As you could probably see from RFC9031, we did make an attempt to separate TSCH-specific from generally-applicable text, but we indeed never instantiated it for non-TSCH setups and additional parameters would need to be registered and described. I do concur that the biggest challenge I foresee at this point is the notion of time.
The use cases you mention are bound to 15.4 radios. Do you see this effort potentially useful for other low-power radio technologies?
