Interesting... Will check that. Costing money is unavoidable, there is no other way to deal with spam and Sybil and some applications absolutely need that protection. More importantly service providers can batch these payments exactly like how Open timestamp works... For example all wallets by definition eventually have funds, say LN, so the wallet Devs are perfectly positioned to do that batching, so is any paid service provider like hosts or relays.
