since #cashu #ecash tokens are bearer assets and there is no blockchain that knows which addresses **currently** hold which tokens, am I correct in presuming that if I delete a cashu.me PWA that has ecash in it, I'm also permanently deleting the ecash itself, and that "restoring the wallet from the seed phrase" in the future is not going to bring the tokens back?

If this is an accurate picture, there is going to be pain along the way in getting people to internalize that. People are used to "seed phrase" meaning "be as cavalier as you like with everything but this and your balance will be safe."

I'm speaking from experience: I just deleted a cashu.me PWA thinking I'd restore from my seed and when I did so and added back the mints and saw a zero balance it was only then that I realized where I was mistaken...
