I briefly tried the demo package yesterday and ran into an error when adding and then viewing a page in the standard Plone UI, no Volto:

Or maybe create a view for use in the traditional Plone UI. But that is double work.
Main question: is it the intention that this demo package is (a bit) usable in the traditional UI? Fine if the Volto blocks do not show up, but it would be nice if view and edit still work.
I realise this is just a demo package, and is there as a demo backend for the Volto UI, so feel free to say: we're not interested in supporting this in the traditional UI.
