Yes, thank you! That's one of my biggest gripes with the W3C stack. How am I supposed to build semantic data, if I can't access the semantics and/or they can change or disappear at any time?

That has been one of the main motivations why I've been working on a content-addressed semantic data/ontology format[0] with a modern decentrelized stack in mind.
