@harding I'm still a little relunctant to saying "No one will ever be able to..". Although what you are describing here is probably true in most cases, if someone gets to know some (or most) of the money you're owning and many of your transactions, that's still a big leak. For instance, someone can send you a large number of small payments and just wait for them to be merged with other UTXO from your own wallet and they'll likely get a lot of information.

Can we perhaps update this text to mention this more transparently?
