The egne/beta/candidate will be used for those who wants to stay on rolling releases.
Most Home Assistant users are used to manual upgrades. Mostly because some integrations changes or gets removed (breaking changes), and if this happens they sometimes need to manually edit their configuration to fit the new version.
There’s a jungle of integrations that ships with HA, but possibly a whole universe of custom integrations that a user can add themselves.
With most monthly releases comes breaking changes.
Another reason that users wants to do a manual upgrade is because an update will cause your HA install to restart and every automations, services etc will go down for a while. That “while” depends on how many and which integrations are in use. E.g if using the built-in Z-wave integration is used, it can take 1-2 days for it to functioning fully.
I know my vote doesn’t count, and as a maintainer I’m also aware of when the next release is pushed, but I would probably be upset if all my lights, automations, sensors etc suddenly stopped working without a heads-up.
