I wouldn't mind a built in voice chat, but this is not something I would personally use. I am simply not a fan of using voice chat altogether, even though I understand the practicality behind it during raids and intense activity (I mainly use it to listen to others during raids and intense strategy planning). However, many users are already using third-party software for that purpose and some already have their server on those, which I doubt they will abandon for a built-in system with greater limitations. That said, obviously, it would benefit the console users, however, it should be made the voice chat client can communicate to external servers as well (to connect with PC users using third-party clients). Also, by having a built-in voice client that connects to external servers, it could take off a load on SE's servers.
