So, I'd like to pass the list back but instead of passing the whole array back in API call I'd rather only pass the subset of that array which has updated = true.

first 3 options which bubble up:
creating a "changed" list on each change,
making a copy of the original data at start and comparing,
enhancing each data item to an object with .value and .changed

option 2 probably easiest to implement, but most likely to introduce lags, option 1 would be my preference if there are only few strategic places which need to be modified/controlled in the event flow.
