- I was able to get my partner onto the tailnet by telling her to install an app and login. She doesn't know or care what wireguard is, but she can now access some of my self hosted services on her phone.
- I'm able to easily dynamically register machines to the tailnet, such as CI jobs
- I'm able to self host a DNS resolver and have it just work for devices connected to the tailnet
I'm sure I could achieve these goals with plain wireguard, but I feel like I was able to outsource significant complexity to tailscale instead.
