I understand your concern, but this is a common misconception. It is not about limiting customization. It is about not letting customization negatively impact on-boarding (the new player experience). Setting these two in opposition is lose-lose for the game.
As you can see, I'm afraid I believe its just that. Can you point at an example of a game with decent, mechanically meaningful customization that does not have this problem? (I make no promises I'll agree with your characterization; note I carefully have inserted "mechanically meaningful" every time I've brought this up.)
