Hi Luke,
Can you elaborate why the current idealized functionality of deposit ->
trigger -> withdrawal is too complicated for
everyday use but the above deposit -> withdrawal ->
resolve(claim/clawback) wouldn't be? I admit at a high level
it's a fine paradigm, but in practice would end
Let's ignore implementation for the discussion, since that's in flux.
Cheers,
Greg
