Well, you can make up whatever definition of "secure" you like. But your
interpretation does not seem to be the logical one, given that:

    1. The ptys that ssh uses have never been marked as "secure"
    in /etc/ttys.

    2. Even if you added "secure" to the definition lines, they still
    would not be marked as "secure" because they're not "on".

    3. Telnet uses those exact same ptys for the same purpose, and did
    not and does not allow direct root logins on them.

I don't understand why you make this point. I think pretty much everyone
here agrees with you that admins can and should use whatever settings
for ssh best suits them, and this change certainly does not prevent that.
So what are you trying to say?
