The argument was not about whether that is the "plain meaning" of the
phrase; it was about whether that is a safe and useful behavior for a
command to have. There is a pretty substantial group of people who
think that it would be quite unsafe, which is why we failed to arrive
at a consensus that this is a good thing to implement.
