In the past, I would have agreed ;-)

I think the current approach is to define a single stable URI for your "semantics/vocab/terms/model" and then as changes are made over time, use the actual "schema/ontology" language to manage that.

In the RDF/OWL world, this is managed by deprecating classes/properties (which is an OWL function) - there are other features such as equivalence etc.
Additionally, in the future, we can use SKOS/PROV ontologies to provide more fine grained changes overtime.

Even XML Schema now has more fine-grained versioning features [1] as part of the schema language itself.
