eGO doesn't ever seem to filter games. For example, our CoD 4 servers allow players to use Martyrdom, even though many servers ban that perk -- because it's part of the game.
We will not be doing this to our servers any time in the foreseeable future. While I agree that some weapons are overpowered, it is still relatively easy to just go a class that counters them well (pyro, scout, or heavy in this case) and shut them down. We don't want to put restrictions on our servers that may deter other people from playing there.
Thanks for the suggestion, but at this point we will not be making use of it.
