isn't the problem with LN as a privacy tool that you would never know if it's privacy assurance was broken? not being an l1 it's not designed to function in the open and if a third party is accumulating information ( IE routing nodes are colluding ) you would never know.
strong privacy assurance is like bolt12, blinded paths and MPP still drastically reduce the UX and ability to move funds.
I agree it's good privacy at the moment. but isn't it just because nobody's looking?
