A beta is feature complete, so tbis demo has eitber descoped stuff for tbe initial v1 release or the demo is a milestone build that will help show progress and take a lot of effort to deliverr. I expect it is the latter and the demo delivery will likely have little impact on beta delivery in the long term due to team recovery from going all out to deliverr the demo, and replacing any stubbed demo functionality that needs to be fully implemented for a proper beta.
