I am not sure if I agree with this article. The semantic web and linked data are built using layers of schemas and Ontology’s and changing old stuff is a bad idea because links get broken. Additive systems, instead of creating new versions, will always seem a bit messy. If you look at valuable public KGs like DBPedia and WikiData you will see these layers of old and older schemas. My argument that this is not such a bad thing does have a powerful refutation: the slow uptake of linked data tech and KGs.
