Same as the other PR—this will need to be rebased, but overall I’m in favor of it! I’d love to approve & merge once tests are passing.

@sadfsdfdsa Sorry, just saw your comments from #810. I think undefined is fine! Better than my having to manually remove the fields with the empty *Ofs altogether. Let me know when I can update my app to use these changes. Thanks a bunch!
