Very interestingly, just yesterday I discovered that VSCode has a set of APIs for adding SSH tunneling, and under normal circumstances you must launch vscode with special flags to be able to use them. Somehow their built-in JavaScript debugging extension can use these APIs without any issues.

And you can hardly find any public information about these APIs. Well, unless someone asks -- As of 2 years ago, they didn't have any plans to "finalize" these APIs, i.e. make them public. You are advised to find other workarounds (which do work).

This is much less "harmful" than Copilot though, I guess.
