 Set `async_payments_role = "client"` to ask peers to hold HTLCs where possible, allowing
 this node to go offline. Set `async_payments_role = "server"` to hold async payment HTLCs
 and onion messages for peers. The server role requires an announceable node configuration.
 Leave the field unset to disable async payments.
 
+Set `enable_zero_fee_commitments = true` to prefer zero-fee commitment channels,

+source that supports Bitcoin Core's `submitpackage` RPC, and relays TRUC, P2A, and ephemeral
