Today, Zapstore publishes to one relay. No one is going to censor any apps on Zapstore anytime soon. Definitely not before I add relay management. It's not "just" about the UI, there are a lot of considerations specific to software releases (not the case for kind 1 notes). Also, unlike many other devs on nostr, I do want to get the spec right- learned many lessons over the past year. No need to pollute relays with half-assed events that then I would need to be backwards compatible with. Keeping things in one relay is much easier for migration.
