I think the list errs on the side of caution as there are just so many factors that have to be considered. The article does have plenty of references and one of them probably has more details on the specific objection to oak. Interestingly, live oak leaves are common choice for leaf litter, so it may be the case that oak falls low on the problem list, but I don't know for sure.
