Personally, I'd vastly prefer that there was ONLY a local interface, and no centralized remote access to everyone's personal data. A remote interface can certainly be useful, but that isn't too difficult or technical to setup with something like tailscale.
While I'm sure the HexOS team takes security and privacy very serious, imagine if there was ever a data breech at hexos that gave hackers/bad actors a list of all the home servers they could target, or worse a direct backdoor.
