No, it's not been a major deal, and I take your point that security is always a trade-off. In my view the particular level of danger in the situation I was talking about was unacceptable, so I fixed something up to work around it, and made a note that it would be nice if it was built into the protocol so that I didn't have to to the same thing in the future. As far as I know, nobody else has come across a real-world instance where they've had to do the same thing, so, if nobody else thinks it's a worry I'm happy to see it go by the board (we can see how the votes stack up on the wiki page). The main point I'd make is that the changes that would be required to the protocol to implement better security than it now has are not very difficult to specify or implement.

P.S. We also lock server rooms round here to defend against axe-wielding undergraduates.
