vim and emacs are over 30 years old and therefore living with an architecture created when most code was trusted. Encrypting network protocols was extremely rare, much less disks or secrets. I don't think anything about the security posture of vim and emacs should be emulated by modern software.

I would say VSCode has no excuse. It's based on a browser which does have capabilities to limit extensions. Huge miss on their part, and one that I wish drew more ire.
