TRAMP actions are also rather slow (high latency). OTOH, tramp-rpc relies on a little tool to run on the remote and is much snappier. This proves there is a better middle ground than TRAMP with nothing and whatever abomination VSCode injects. Basically, busybox with a persistent RPC connection is all one needs.
Latency can be managed by having shared connections (for example: https://tanguy.ortolo.eu/blog/article42/ssh-connection-shari... ), so handshakes don't make everything super slow
