I don't use ssh-askpass. [1]

I can confirm that with gnome-ssh-askpass installed and configured, I
get a pop-up box.

Is there no way to confirm user presence via the tty when using the
agent?  If not, a note to this effect is probably needed in the U2F


[1] I've tried ssh-askpass in the past; my (flawed) recollection now is
    that with long-running jobs which would eventually get around to
    trying to connect, I'd get interrupted and focus/keystrokes stolen
    and it aggravated me.  That, or it was frustration at the Gnome
    stuff always trying to cache passphrases in login keychains and
    checkboxes defaulting to "yes" every time, so I just nuked those
    bits from orbit so my "remote access to sensitive systems"
    credentials would not be held inappropriately.
