Agreed.
In contrast, BIP37 as used today is totally decentralized, and can me
made much more secure, private, and scalable -- without giving up the
utility of unconfirmed transactions.
Please don't read into this statement a belief that all the coffees
should go on the chain, or that the security or privacy of BIP37 compare
favorably to any other particular thing.
