> lack of HDMI
I'm generally fine with lack of HDMI if it means more DisplayPort-enabled ports. Historically, I've found having HDMI as a standard to create more problems than solutions.
DP->HDMI is a pass-through but HDMI->DP requires active adapters which may not always exist for a certain required bandwidth (and may not suppport features such as adaptive sync). From this standpoint alone, it's better to have all ports be DisplayPort (or USB-C with DisplayPort).
In the past, computers have included non-4K60-capable HDMI standards when 4K60 support already existed with DisplayPort. These models would have been functionally better off including DisplayPort and letting people step down to HDMI as needed.
Some existing montors support 4K at higher refresh rates, but only through DisplayPort and not HDMI (as they have 2.0 ports).
HDMI is one place where I will endorse Dongle Life, because the main adapter-related concerns with missing USB-A ports (compact accessories no longer being compact) and missing headphone jacks (unwieldiness on the go) aren't really at play with connecting displays. And you get so much more flexibility with DisplayPort.
Unfortunately the lack of HDMI here doesn't lend itself towards another display-enabled port, though, as there are still only two USB-C/DisplayPort connections. It would have been nice to have three.
