IMO depends upon the oil used.
To me, it is a "why not?" situaton. If your car doesnt use a special break-in oil, then why not change it early, get some fresh oil in there and get used to working on your car? If there is ever a time when there could be some junk in there, it is when the engine is new.
That said, if the oil is a specialty product, like the high Mo oils that Subaru and Honda use, then I'd change it by the book, as there is method in their madness.
I like to pull an early UOA if possible to help see what kind of oil is in there and if there is any early flag. It wont trend anything, but there are certain things you can look out for.
