That "legacy video port" supports cable runs of lengths far greater than USB-C, making it way the hell more useful for lots of use-cases. Plus most of the rest of the computing world still ships HDMI, so "I can't plug in to this" is mostly a Mac problem, and only solved well at places that are Mac-only or Mac-mostly—everywhere else, you better tote your stupid, expensive dongles around with you. Basically, Apple's been pushing USBC-only for over half a decade now, and you can still plug directly in to 99% of video devices in the wild with HDMI, and only 10% (even that much? Probably more like 1-2%, because so many video displays are TVs) with USB-C, without resorting to an adapter or special cable that (again) users of most other brands don't need. It's not "legacy", it's "not that weird crap that only Mac users need".
