That's the end result but don't assume it's intended. Has Epic ever stated that their store would be DRM free? If it was intended and that's a feature of EGS then you can be assured Tim would have been singing its praises from the start.
They have always said it was up to developers/publishers to choose if they wanted DRM or not. Many games on the store are DRM free. Even if the case of Borderlands 3 is a mistake, 2K messing up their DRM implementation isn't a "security flaw" in the Epic Games Store.
