I'm not buying a new monitor with a decade-old version of DisplayPort. Non-oled monitors are products that last a long time (at least a decade) so if I bought this monitor, I'd still be using DisplayPort 1.4 from 2016 in 2036. I need UHBR20 on a new monitor so I can rest assured that I will have some lanes available for my other peripherals. I've already lived the hell of needing to dedicate all 4 lanes to DisplayPort, leaving only a single USB2.0 connection remaining for all my other peripherals to share[0][1].
