I’m not arguing about what is technically possible. I’m arguing about what is practically possible: Samsung (biggest market share) supports LC3 for example, but they can also break it and replace it with their custom codecs to lock people into their ecosystem. Making Sony LDAC the only real choice, and there’s no telling when they will break that too. This means that in practice, only SBC and to a lesser extent AAC and SBC-XQ are the only codecs you know for certain will work.
