There are many others examples that show how the Glossary is not complete.
The Glossary looks like incomplete, there is literally a TODO (there are several). And also the format of the text IMO can be improved. A sentence should start with a capital letter.
Yep the glossary is a work in progress, there is a lot of other content that is a lot more mature and that you can focus on 
I have changed the glossary to make it more explicit that this is a work in progress, so probably not worth reviewing for now.
Tracked in github.
