I'm not familiar with the state of Umbrel or Start 9 or other popular node implementations but do they offer self-hosted ZAP servers yet? I can understand not spinning up a server if you're not technically inclined But if you're already running a node and there's a one-click option, it's not really that much of an extra step to take.
I guess you do need a domain for lnurl soooo mmmmm. Damn. Even a one-click install would I guess take some extra effort and a domain.
