Video chat apps that don't mute crosstalk

One of my biggest pet peeves/downsides of video chat is that they (by necessity) mute all other lines when someone is talking, to prevent feedback. If everyone is wearing headphones rather than listening via speakerphone/computer, it's not longer necessary to do that.

When crosstalk is muted, it removes a huge interpersonal dynamic in natural conversation. If I can convince my team to use e.g. airpods for all video calls, I'd like to find a video service where we can talk over each other as well.

Do you know of any?
