It makes sense.
As far as settings, Collect can be configured via QR code and the Central server uses this feature to help devices connect to it. Central's roadmap over the next year includes a feature to sync forms, submissions, and settings so device setup and management will be a lot easier.
Onboarding is a totally different issue and I think it's something that we should consider adding. What are top five or six things you'd want the user to know about? Is there a data collection app that you think does this really well?
