Let's say this a bit more clearly. (The restatement in `undefined.validity.maybe-uninit` already reads OK.)
The placement of the new items didn't follow the ordering convention used in this list. Let's fix the placement of these.
The proposed wording here was taken from the documentation in the standard library. That text is a bit loose. It says that the type is "used to construct uninitialized values of type `T`", but of course we're using it to construct *initialized* values of type `T`, not *uninitialized* ones. And that's only one use case. It's indeed a bit tricky to concisely describe `MaybeUninit<T>`. Let's try to do a bit better.
