I know the paper is lacking in evidence, but it proposes such an interesting phenomena. It's worth exploring more.
It made my mind jump to perhaps a second, potentially worse outcome of mouth breathing - seeding the lung mucosa with oral flora. That seems like it could enhance the spread and inflammation. And cause deleterious downstream impacts such as slightly increased risk of cancer, pulmonary diseases, etc.
