Yes, probably. I would also recommend carrying the notes in an EMF protected wallet. We have considered a feature which explicitly lets you back up the user keys from notes so that you have this as a fallback claim, but this might also encourage people to just "mine" notes in the hope that someone doesn't re-key. Given there is nothing we can do to prevent this...we might build it.
