Privately sending payments while offline with BOLT12

That was exactly the goal of bLIP-0028: Paratonnerre by t-bast · Pull Request #28 · lightning/blips · GitHub , which can provide good security by pairing your remote node with a hardware wallet (e.g. Ledger or Coldcard). I still thinks it would be very useful to standardize the control messages in this bLIP.

Does bLIP-0028 do any onion messaging?

Also, at a high level, how does bLIP-0028 differ from what https://vls.tech/ attempts to do?

bLIP-0028 looks cool for a lot of use cases, but I’m wondering if it is much more complex in its feature set than what I’ve proposed for simple invoice payment with a merchant.
