sshd is "used by over 50% of its users without passphrases" ?
You mean it is used with public keys INSTEAD of passphrases.
By your own statement, you're apparently smarter than the 50% of ssh users who rely on public key authentication. Obviously, they all missed the huge, gaping security hole exposing their hosts and source code repositories to attack. That's why ssh remains the #1 attack vector to this day across the internet. Right?
At least -e is in the man page, plainly documented.
Your diatribe is severely misleading at best. If you aren't trolling, then it's no wonder why nobody takes your advice seriously. And if you are, I just typed all this crap in response to, essentially, a Rush Limbaugh cartoon.
