To note that Pocket was related to web browsing and offered a convenient bookmarking system. The reason people complain is it being a third-party extension and service (requiring registration even) rather built-in features in the web browser.

That said some functionality has been included in bookmarks such as clicking favorite button saves directly in unsorted, clicking twice opens a menu where tags can be added, and can see all bookmarks through menu. A secondary bookmarks tree can be added with extra features being read status, and simple status change and deletion from menu without requiring right click. Kinda like Chrome did it.
