Exactly. You also won't get to see the original intent in action from an operational standpoint either. Over the years I'm sure you've come across an architectural item or something and wondered why they made it that way. Often during the opening days they run things by the book as intended. Later they stop using things that confused guests, caused backups, etc...
I would say the one exception to this is Diagon Alley which never used many other of the doors their shops have - and still don't - to limit access in and out of the small spaces. Quality Quiddich is the best example. One door is always blocked with a display or sales rack. But the on the flip side, if you went early you got to see the store queues in use, the Owlry, and the original Shutterbuttons.
