A few years ago, [0] made the following point in regards to password input feedback:

> For a time, there was rich pickings in applications that accepted passwords in unbuffered mode. Many of them doing it so that they could echo "*" symbols, character by character, as the user typed. That simple feature looks cool, and does give the user feedback ... but would leak the keystroke rate, which is the last thing you want on password entry.

This was in response to keystroke timing defense on SSH. Does this feature still come with the risk of leaking keystroke timing to an attacker with recent OpenSSH/Dropbear versions? If so, it might be wise to keep it disabled on servers.
