Add Full Page App Component Type
It's been brought up multiple times in different places, but I'm not sure if this is the same issue as other SPA-like suggestions linked to at the end of this submission. I think this would give us the ability to deploy a SPA so IMHO this could be merged with all of them.
I'd like to have a new component option for SPFx projects: full page app. I want to define 100% of what goes into the canvas, blocking the user from making any configuration changes in edit mode. Ideally I'd like two types of pages to write to: one with & one without the QuickLaunch menu (if QL isn't present, take up the entire user area of the page... what we used to call "PlaceholderMain"
When a user installs the app, the page is created somewhere (maybe the Pages library) and optionally a link is added to the QL.
Think of it like this: it's like a modern page that allows the developer to add a single web part to the canvas and disables edit / delete options for the page by designers.
