Yeah, locktime is one of them. Taproot channels set nLockTime=0, which a bunch of stuff doesn't do.

Thanks. Can you be more specific about these distinct characteristics? Fingerprints like locktime, version, & RBF flag should be able to be fixed, right?

If the private channel is cooperatively closed using the Taproot key path, it won't be known as a channel open.

It's not obvious at least. But transactions for taproot channels have distinct characteristics compared to transactions made by lnd's wallet (and probably other LN implementations). So an adversary may still be able to detect that by heuristics.
