"secure" is a complicated word :-) I see your point about authentication
and integrity, but it breaks the property that if you use ssh then you
are sure there is no way to end up without encryption.  (I get it that
with TOFU you aren't sure you are sending data to the right place, but I
see that as somewhat separate.)
