The whole point was I don't care if the whole world knows our proprietary extension. No virus writer is going to waist time pointing her 0-day worm at us. The whole idea is to spread as much as possible, so they will pick standard extensions only. If it is not a 0-day, our AV server will kill it anyway. This mehtodology has stopped 100% of all virus attachments since institution. Our AV server is getting bored, having nothing to do. In addition I don't get up at 5am anymore to scan the lists for the newest outbreak. The peaceful sleep alone is proof of it's usefullness.
