Comment 5 for bug 1708291

I built fresh again and tested from Kathy's sign-off branch, and things look really good. This is such a gigantic step forward, and I am looking forward to working with this in the near future! Thank you to everyone who helped design, test, fund, code, and overall make this a reality.

I have one very tiny follow up commit which I hope can be indulged (just a code-level name change in the MFHD module). Will push a branch shortly.
