Its a trade-off. Many people do provide constructive first posts, and having a delay between User creation and basic editing rights might make them forget to do it, or loose interest.

At the same time, the Vandal problem we have is by a fairly dedicated person(s), it might not even have an effect.

By far the most effective thing we can do is to not engage them (in case they are doing it for attention) except by to revert the changes as soon as possible, and report them to admins/VSTF. Even if we can't make them stop, there are way more of us that undo their work than there are vandals.
