Practically speaking, I don't see why that would be important in this case as the wallet isnt identifiable to me, im not buying kyc, and new addresses are generated each time. If it were easily traceable from liquid wallet to wallet, that would be one thing, but its not. One could make the case that the timestamp and short list of possible pegins would be a weak point, but you need a lot of information going in to track liquid whereas onchain is wide open.
