There are two opportunities unique to payjoin to reduce fees beyond opportunistic consolidation (consolodating the incoming sats w/ existing sats can share the overhead of 1 tx)
1. transaction cut-through or forwarding: if you spend the incoming sats to someone else straight away in the same tx, you are never encumbered by fees to spend a utxo since you never take one
2. Overhead. Though indeed receivers do pay to add inputs to a payjoin, the marginal cost should be less than if they were to create their own tx to spend them since the sender is paying for the overhead of the tx header, making batching even more cost effective.
I have written the mechanics of how this could be coordinated here on substack. A few enterprise wallets have expressed interest especially since it hits their bottom line.
