During COVID I had the wonderful opportunity to remote into a work computer that had a Matlab license and watch the screen slowly paint in. Each keystroke took multiple seconds to display for me.
Love the ability to just forward one or several applications directly instead of the whole desktop environment. Ability to resume connections are also a godsend.
Seems like that usecase isn't given a lot of effort nowadays.
But this is an "XY problem" situation: what you want to get a GUI app running on a remote system to have its window display on the screen in front of you. Xvnc can accomplish that.
