I use Display Port on my main PC monitor. Recently I added a secondary screen, a bigger TV screen, just to watch films on it. Neither I have a second Display Port on my GPU, nor have the TV any. So we are stuck with HDMI to a degree.
UPDATE: Even more exciting... Per this comment from a prominent AMD Linux developer, it looks like a full HDMI 2.1 implementation for AMDGPU could be coming!
They already mentioned DSC is lined up to go out but still needs compliance testing, so the code is probably ready. The "could" wording is by Phoronix not the AMD developer.
This work was already finished 3 years ago but couldn't be sent out due to the HDMI Forum blocking it.
4K 120Hz is a really common TV input and even this is not possible in HDMI 2.0 without 4:2:0 chroma subsampling which is visually lossy especially in desktop usage.

Valve is probably adding that to the Steam Machine as we speak.
Also, fuck the HDMI Forum!

That's why you don't challenge a open source developers. They will code you out of relevance.

correct. in terms of supporting more hardware that is out there, this is very welcomed

Yes but if a GPU has DP it probably comes with HDMI, meaning they can still get your money*.

Given the issues we have with dport right now, I have to say that reason is masochism and a hatred of features.

Could be, key word "could." I'll believe it when I see it.

I feel like this whole HDMI 2.1 thing is only an issue for a minority of people with ultra high end expensive monitors, and is overblown as a result.

I'd wager that people who have linux and are plugging in TVs to run at 4k 120 are probably also not significantly in the majority.
i mean, sure, do it, we deserve to have feature parity with windows, but its not a problem that is affecting the masses.
