Yes this is the ideal space for a performance minded web rendering engine rewrite. And if you do it well enough as a subset it can become the next standard where the modern web is just the subset, you can even integrate it with a legacy render where you fall back to legacy when you detect you cant handle it, and have the fast path for the subset.
