As someone building a business off of VR in the browser, I think we should always have a fallback. The systems we use for building the web--whatever they may be--should do more to encourage accessibility, rather than leave it as an "exercise for the reader", aka "afterthought". Users of these systems have a legal responsibility to make their site accessible. As framework developers, I think that we must share that responsibility, at some level.
