On the majority of nodes I provide Tailscale SSH access to, it's as root or a user with passwordless sudo. It's being used for admin access. So yeah, on those it doesn't matter as much.

There are a handful which restrict users to their own user accounts. But it's on dev server with friendly devs, so even for that use case it's not really the end of the world.

I'm sure our infosec folks are going to demand that we upgrade everywhere, however.
