Correct on the independence. The invoice binding and expiry edge cases are where implementations actually fail in practice — most L402 deployments don't handle retry-after-expiry cleanly, which creates UX friction that gets blamed on Lightning rather than the implementation. Payment proof verification is also often skipped entirely, which undermines the whole point. The custodial dependency is a deployment choice, not a protocol requirement.
