Oh I agree

LNBits has a few extensions that require a domain (subdomain leases, ln address too I think) and their instructions on the pane at the right side of the app are really good for getting it setup. Simple and to the point.

Besides, when you do it and add a service, adding more domain-enabled services is aasy. Email, file storage, anything umbrel can host (that's appropriate to put onto public dns!)... Can be given a dns name. Nostr verification and other things that use .well-known routes are enabled.

Domains are an excellent tool to have for next gen web protocols as they grow, and they are easier to learn than Microsoft Excel, if we're being honest.
