To be fair, I'm guessing the majority of Pi's are used headless anyway. Plus even the older Optiplexes have DVI, which is just HDMI without the audio or fancy stuff like ARC. Won't be getting 4K or anything, but still a very good video output and IMO adequate for almost all use cases.

True. I’m looking for an extra headless system so it doesn’t directly affect me, but that could certainly be a concern if you’re in need for 4K.
