If there was in game voice chat I'd keep it disabled. Preferably it won't auto stream in the background. Because yech. Something irrelevant to add to the loading of everything else. Nty.

It won't be long before people start complaining about encounters where people abuse in game voice chat by either being creepers, making annoying sounds, or playing awful music... it's a bad idea.

At least with 3rd party voice chat programs we can choose a selective group of people we can listen to and it's within our control to kick out and mute troublemakers as the group sees fit.
