Yes, I did mention that there are worse things that can be done with social engineering, especially involving /run
I've been scripting for years (I'm a sad IRC addict >.>) and I've never ran into a situation where the speed of packets has mattered to me when sending out commands to the server.
Perhaps LF filtering could be an option that's on by default, so if one uses a script that uses it (I can't imagine why or how though, given my above stated experience and since we have /raw) it could be allowed.
And like I said, it's low severity.
