As I said before, once the prerequisites for a better notification
method are usable in the network, I'd love to define a version 2 payment
code that uses such an better notification system.

In the meantime. every block mined shows very consistent 70% address reuse.

Anything that can bring that number down is a good thing. Even if
version 1 payment codes could only potentially drop that number from 70%
to 30% instead of to 0%, they'd still be worth using while we wait for
version 2.
