I think this is getting blown out of proportion. These plugins are a big change by tf2 standards, but peanuts compared to other esports with active development teams. Not only is there more change, it is also less democratic because the developers can do whatever the fuck they want and everyone has to deal with it. While only the popular plugins will get any use in tf2.
So yeah, this is a trivial change by comparison. So trivial in fact that i didn't even notice the plugin when i played a mix with it the other day (on soldier). I only realized when people were talking about it after the game.
