The Bookmarks page is apparently quite new; I also only learned about it a few days ago. Whereas I discovered the “Enter focus mode” feature on Q&A posts by accident; I don’t know how old it is, or why it’s only available for Q&A posts. Maybe it’s an experimental feature.
I have two three year old booksmarks, so while some aspects of the page might be new (like being able to see the post on which you voted), bookmarks seem to exist for longer.
