No doubt some would use it and it would be amazing, but I trust that MFC knows the majority of their user base (models) are not equipped to use it so it is not a priority for them.
I see models as content creators. And patrons as users.
Because of this, I see many 'users' to be ready for HD.
CB has up to 4k. Sense the change, most content creators are streaming at least 576p. Which seems to be higher then MFC max resolution. But if you look at the top 100, they're all at 1080. Some of them are 4k.
I don't think MFC needs every content creator at 1080. They just need the big content creators to be able to stream at 1080. They need to be able to compete in video quality.
