Do all your users alias? (assumption: its more than just you on the system)
Do you check the alias is set everytime you login to a session?
If you change to another shell for any reason is the alias persistent?
(eg as root (defaults to csh) some times I have to do: sh -c 'for a in x
y z ; do ( cd ${a} && rsync -e ssh remote.server:/path ) ; done' ) - and
do other users know that this would be wrong?
See the point I mean?
For the security conscious one would know to use the full path of ssh,
most do not do this... a large percentage have no idea that they would
even need to let alone remember.

PS: There is a workaround for ssh clients in /etc/ssh/ssh_config to stop
it falling back to "insecure" protocols - though every freebsd-update
attempts to change this file back to the default... fortunately I have
puppet to reset the file in the event of me missing the update/reset.
