I just merged patch https://gerrit.wikimedia.org/r/#/c/243024/ to remove access for user handrade.
It appears that they had no bastion access, but stat and anaytics boxes access (so if one of these has a route to the web without a bastion, it would have been accessible, and therefore make them all accessible.)
I'm not sure if this is a concern or not for analytics, as they worked with this user and would better judge.
