nowadays most people use Django to create REST API. I wish Django would merge DRF into its codebase.
Plus it already has decent async support.
I doubt that's true, but yes, having DRF merged in would be rather nice.
My best guess, and I have nothing but my own experience to back this up, is that for every public facing Django based website, there are at least three used internally and at least one of those use nothing but the build in admin interface as a UI.
