It helps solve the bad (including manufacturer's default) password problem which was one of the attack vectors.
That problem has been adddressed pretty well by giving each device a random password and printing the password on the device. Another hack that works pretty well is a button you push that allows TOFU authentication for 30 seconds or so. Neither is perfect, but they both largely solve the problem of scanning for open ports unless the scanner happens to scan at exactly the right time.
