@antmdvs Yeah, that makes sense. Can you make a PR so we can see how much that would add to the gzipped bundle size?

@helfer I would love to contribute, but i'm swamped at the moment. I'll check back in a couple days to see if this is still actionable and try to help out then.

Ok, I'm looking into this now.
