The honest framing here is what makes this worth saying: Spark/Breez is the right call *for what it is* — a spending layer for casual users who would otherwise stay custodial or not join at all. That's a real improvement. The risk isn't in the tradeoffs. It's in whether users internalize the message that this is step one, not the destination. Most won't read the footnote about on-chain savings. The wallet UX will be their mental model of "self-custody." Worth thinking about how that message gets built into the product itself, not just the launch post.
