Yes, I like this model. It's easy and it's obvious ("'x' for hex"),
and it gives people a good way to say "yes, I really want the actual
address as hex" for if/when the hashed pointer doesn't work for some

So me likey.

And as with the address leaking script, I'd like it even more if you
made it a git tree and I'll pull it.
