The draft for BOLT#12 (Offers) introduces a new payment flow where the receiver of funds posts an Offer. The Payer can then request a unique invoice and pay the invoice. There are significant improvements in the flow including payment and payer proofs.

In a Key Send payment, a payer can send funds to a receiver without an invoice by encoding the preimage in the onion payload for the receiver.

Let’s say in the context of donations, a receiver can either post an Offer to use the BOLT#12 payment flow OR post their node’s public key to use the Key Send payment flow.

Am I correct in thinking that BOLT#12 is an improvement over Key Send payments? Or are these two solutions solving completely different problems?
