I really enjoyed my time with Vault's ssh-ca (back when it had a sane license) but have now grown up and believe that any ssh access is an antipattern. For context, I'm also one of those "immutable OS or GTFO" chaps because in my experience the next thing that happens after some rando ssh-es into a machine is they launch vi or apt-get or whatever and now it's a snowflake with zero auditing of the actions taken to it
I don't mean to detract from this, because short-lived creds are always better, but for my money I hope I never have sshd running on any machine again
