Have you got any reason to believe so? Muse code is a black box for us, so we can't make proper estimations on the work effort needed to implement certain features. Personally, I'd be surprised if adding an additional channel to the match chat window took more than altering/adding one line repetitive of code as a multiple channels are already displayed in those chat windows... perhaps it's even as simple as editing a config file. That put aside it's just removing one of the chat windows which converts the UI section to a state that already existed once (just global + match chat). I don't see how this can cause complications either.
