I've only skimmed this, but it looks like a solid set of improvements.

I'm happy to re-read this section again once this is merged/released.

Also, I'm seeing where semantic linefeeds would be super useful.

Perfect, that's what I was hoping for. I'll merge and post a new draft to the Trello card. After a general thumbs-up there, I'll update /release.

Thanks again.
