Isn't just better to enable autosave? (VS Code has that as well). I learned its usefulness from PHPStorm, where it is switched on by default. So I just not explicitly save anymore, it is done automatically and immediately.
Hot exit is still useful when auto save is on as it works with untitled files. Crash recovery also comes with hot exit regardless of whether the feature is on or off. (I'm on the vscode team)
