Actually, a lot changed since the launch of the VT100, but most of those features just haven't survived into modern terminals and/or people don't use them.

E.g. Sixel, ReGIS, html output, terminals treating the scrollback buffer as a live document where commands can be re-executed. AmigaOS let you auto-complete filenames using a file requester.

The hard part is becoming so seamless that it integrates into peoples workflow to the point of being something they're not willing to live without, and none of the above really succeeded at that.

The terminals I use have Sixel and ReGIS enabled, and I have a shortcut to output images to the terminal, but I still often forget and open a separate image viewer anyway, for example (but it is awesome to be able to display an image from a remote server directly over the ssh connection, but that depends on a utility script on said server).

Instead we revert to the lowest common denominator because it's good enough and other things, like latency and being ubiquitous across platforms matters more.
