Why not? The only thing I think you could reasonably say is that it would be nice if there was a built-in way to freeze the game at a certain state, so that you can still play, say, Stellaris 2.0 if that's what you liked, and not get any of the patches that essentially assume you'll also have certain paid DLCs to function fully.
But Stellaris 1.0 and all the other were massive games people enjoyed playing, they weren't stripped down skeletons to build DLC on.
Were they as good at release as they are 8 years later? Not at all. But having them change and generally evolve over those 8 years is a key part of what makes people still play Stellaris today, when many other games from that time have long been abandoned.
Not to mention, plenty of people would have actually preferred it if instead of Civ VI and Civ VII, we were getting Civ V 4.0 today.
