What? All are niche, and video calls are at best quite rare. People still prefer audio calls or even text messages mostly. Video calls is just a feature expected on smart phones, and it means there we better have an hardware encoder. I don't know if AV2 is defining them, but it needs hard "profiles", that to give a scope for hardware implementations. Well, it all depends on how AV2 is designed, and defining those profiles is very probably a feedback loop between the AV2 designers and hardware implementors.
