Add a little mixnet in there and you also get rid of the temporal correlation (feasibility still to be shown).
yes-we'd always figured a true high-latency mixnet would be incredibly useful for bitcoin transactions, it doesn't matter if they reach the network a few minutes later for lightning, which has more need for roundtrips, the added latency of even Tor affects payment routing and the user experience negatively
💯 for on-chain tx's that would be amazing to have.
