Enforced disposable address feature (EDA), currently a work in progress. This change in the consensus of miners will enforce a single input for each address in a way that no one will be able to reuse an address to receive payments. This should discourage taint analysis or the classical 1 address 1 wallet behavior that can harm privacy of many users on the bitcoin network.
If the dev will really be able to deliver this feature, it will be a very interesting semi-anon coin
