If I understand right those two PIPs were note even implemented... as of yet. It would be nice to implement at least PIP-0012. If one doesn't move coins for 4 years, it doesn't mean those coins are permanently lost, so speaking of coinrot is premature. In fact, if the devs goal is to fight a coinrot, that inactivity period should be changed to 80-100 years at least, to imitate a person lifetime. Having it at 4 years smells like a forced nationalization (basically - misappropriation) of money, much similar in effect to government printing money and causing a dilution of people's savings.
