I agree it’ll likely be few devices that’s ever see an update but I think theoretically Zigbee proton supports OTA from the hubs. I know home assistant supports automatic OTAs from a handful of brands.
I'm really glad I went Zigbee as its been almost completely pain free even with third party non cloud software.
