> I don't think so, at least at this point. Most people don't have hardware that requires HDMI 2.1 in order to get full use out of them, and of those who do, not all of them use Linux and/or care about open source drivers.

I do, but this hardware doesn't have DisplayPort. I switched from Nvidia to AMD specifically for the open source Linux drivers, so I'm quite mad at the HDMI forum for this.

On the other hand, my next TV likely won't have DisplayPort, either, because almost none of them do, so it is indeed questionable whether this is going to loose them any mind share.
