No. The X protocol is objectively shit. It's so shit, modern toolkits don't even fully use it anymore. Instead they do all rendering locally and pipe the composited pixmaps over to the X server via DRI. Over a network, guess what? No DRI. Meaning uncompressed pixmaps get sent over that network link every time a redraw happens.

Wayland, Pipewire, and H.265 will be a much better general solution to remote desktop access. In the meantime, VSCode via browser is a MUCH better approach than trying to forward it over X over any but the fastest network links.
