I guess that is an ever slight difference, but not sure if it is significant. Why else would you be sending to a mint (if that address is known and associated with a mint)? Will at least evoke major suspicion

And if you p2p trade or atomic swap for Monero - this is essentially the same thing as sending Bitcoin to a mint. Probably even better. No one will know you got that Monero aside from your peer (and you'll also likely be anonymous or pseudonymous with these methods too)
