It did cross my mind. However when we had the steamcmd update on the test server with the patch that all the other servers are currently using, the microphone sounds were terrible, so they decided it would be better to have the old build. I have a very small hunch that this might be caused by dproto in SOME way, but can't be sure unless its actually tested.
Note to Raven, when you are on ts3 (and you are free for like 30 mins) and you find me online let me know so we can make some hard core troubleshooting.
