VS Code isn't doing this with text or graphics, though. In X terms, it's running both the client and server on your local machine. It simply doesn't put the network boundary in the same place as an X application.
VS Code's "backend" that runs on the remote machine is rather only in charge of more "asynchronous" operations that aren't part of the UI's critical path, like saving files or building the project. It doesn't speak anything as granular as the X protocol.
Classic UNIX program architecture in distributed systems, apparently some knowledge lacking here.
Long are the days using pizza boxes for development it seems.
The comparison you made wasn't to arbitrary distributed UNIX programs, though. It was to X applications, which don't work this way.
