Maybe it is time to move to something new

Also why does sshd run as root. I deal like ssh could use some least privilege

Preliminary note: OpenSSH is one of the most secure software in the world; this vulnerability is one slip-up in an otherwise near-flawless implementation. Its defense-in-depth design and code are a model and an inspiration, and we thank OpenSSH's developers for their exemplary work.

When you log in to an ssh terminal for a shell, it has to launch the shell process as the desired user. Needs to be root to do that.

SSH has been around a long time. It's not perfect, but it's mostly validated. Anything new won't have that history.

Can't it use built in OS mechanisms for that? Surely you could figure out a way to only give it permissions it needs. Maybe break it up into two separate processes.
