I don't use code editors, but when we had an issue with ssh sessions hanging, it was always coworkers that were using vscode and connecting something up with that.

Man, just ssh through the terminal like a normal person and transfer files with git.

"Man, just put it on tape and walk over to that machine to load it there".

Sorry, I know such low-effort puns are shunned on HN, but once in a decade I grant myself the permission to not resist.

Given my experience with the vscode remote instance, that actually sounds terrible as it can get bloated very quickly. The instance state can and should be retained without running the instance indefinitely.
