A podcast I listen to with 4-5 people talking in a room does that with its audio. It sounds like a good idea, but in practice, it drives me nuts and makes me feel like I have plugged ears. I always enable mono audio when I listen to it.

I think if it was dynamic, where turning my head towards the person speaking balanced the audio (like in real life), I would not have a problem with it. A super simple form of virtual reality that would only require a simple head-mounted gyroscope or motion sensor.

Another podcast I listen to has two people with very similar voices, and I sometimes have a hard time figuring out who's speaking, so I welcome any advancements in this space.
