That list doesn't seem exhaustive in the least. A modern example is Fogbank, a classified nuclear weapons material that we recently had to reverse engineer to successfully rebuild certain warheads.

Despite having the actual engineering documents, we just don't have the manufacturing skill to rebuild one: https://apollo11space.com/why-cant-we-remake-the-rocketdyne-...
