I appreciate that Tailscale runs the DNS server so it's one less thing for me to manage. Similarly, the built-in LE is just icing on the cake as it's one less thing to think about. Once https://github.com/hassio-addons/addon-tailscale/pull/89 is merged, running Home Assistant on a VPN with a LE certificate, would be such a quick setup for anyone.
Indeed, you can do all that yourself as you point out. Just last night I manually created a public domain to point to a ZeroTier address and ran the Lets Encrypt addon in Home Assistant to generate a certificate via the DNS challenge. Didn't take long, but there were many steps involved (creating a Google Cloud service account and configuring everything).
