I think Primitive started out with a bang under one of the many false dawns of XR and while it is still a side project, it is not super active although I did see JavaScript added in the last 6months so definitely not frozen. Your own project looks like a great experiment with Apple ecosystem and while I hope they join on to standards based WebXR it will be good to see this new development environment they are rumored to release this summer. I had not seen TapKit before so thats a great thing to be aware of thanks & it reminds me of a project called Lexting that was floated for a while using freespace inputs and still some demos on Youtube. Good luck with your prototyping!
