It doesn't completely replicate it though, does it? No iOS app, no file sending -- heck the entire premise of Tailscale is oriented around SSO as they are explicitly not an IdP. I don't mean to knock this effort -- it's great! -- but even if I were to switch to this today, there is a ton of missing functionality, and I'd need to do a ton of work beyond the scope of Headscale just to get this running in my corp.
