So in a nutshell the script would make it possible for users to gain from transactions fee by accumulating dust that would barely have effect on the fee of miners.
Would the fee threshold be fixed? Or subject to fee and if so Who would have the authority to and what's the time interval.
Given enough incentive, a miner can try to drop some block, and mine an alternative version, if it could give a bigger reward in a lottery. It is similar to reorging a block with 10k tBTC fee:
Wouldn't this be too expensive to implement.
