Yeah, that would be fair. Personally I just want it globally disabled, idc. But maybe there's 1 in 100 times I do care and can turn it on, that'd be nice.

Frustratingly, built in Mac displays kinda force enable it. You can at least reduce the max nits to be the same as max screen brightness, rather than the insane "XDR" default where HDR can go nearly 3x the max brightness. You can also make a custom color profile that disables HDR, but this disables the screen brightness controls, which isn't worth.
