yes I agree. Thats the reason I have my own prop tree where further
processing takes place. Eg. take the AP altitude and push it out on the
assigned 7segment displays, decoding the number to the way the 7segment

no. my idea is to be based mostly around the property tree. when some
subscribed-to value changes, push out the notice with the new value.
