Best would be to use a proper license, especially if you plan on using these features. Even if the objects are already present for another site. Not importing these type of items removes all bindings to it for your new site. Meaning they will not be automatically restored when putting in the full license.
Also note: not sure if this is development or actual production instance, but be careful that some global tasks might not be running properly when triggered by the "free-edition" one.
