Does it really make sense to add multiple hops though?

After all just with one lnproxy hop, the lnproxy admin only sees the payment hash and the destination pubkey (apart from the amount). But does not know where did the payment come from (only though which of his channels he received it). So adding more hops does not change that 🤔

Additionally, proxies support paying BOLT11 blinded path invoices, so users are probably better off by creating a blinded path invoice that hides the destination node, wrapping it, and sharing a regular BOLT11 invoice that any LN implementation can pay. While hiding the destination pubkey 😎
