I've opened issue #4463. We should tackle it during hacktober. I think that should be implemented before we can merge this PR.

That seems like an interesting approach. We currently 'Roll Our Own' implementation, but I would consider a dependency for it. It doesn't seem to play nice with emojis, I've opened...

Could we add a "deprecated" message to the top of the repo?

Yes, svg is notably missing. I remember back in the day not having time for it. Feel free to create a PR for it.
