this is how microsoft's remote desktop protocol works (RDP) but apple never invested in their implementation of something similar, relying on vnc to just send images of the entire screen.

the way RDP works is the code to actually render a window or desktop gets sent over the network and is ONLY rendered on the remote client.

this is not only more efficient but also allows for fun things like rendering remote apps directly on your local desktop mixed in with your normal local windows
