I already covered your first point, you don't need to.
As for your second point, autosave still does its job. The fact that you haven't chosen a name and a folder for your document doesn't mean that the software hasn't created one on disk that keeps getting autosaved. When you decide to finally save the document, that file gets renamed and placed where you want it.
I mean this is trivial stuff that got solved a long time ago, I don't see people on this thread saying I don't trust electronic payments, I only write checks but somehow everyone think a basic feature is broken everywhere
