You create a project, paint an arrow in its image and then export the project to a flattened PNG file. GIMP rightfully complains when you try to exit because you didn't save the project. There's no format-pushing agenda behind it (like, WTF would that even want to achieve?), it's just common sense. Basically, you're angry because GIMP doesn't optimize its UI for MS Paint use-cases. Trading "slightly better for basic usage" with "significantly worse for any other usage" is a bad idea for a software aspiring to be a professional utility.
