"The argument that users who need this information should know how to get it is absurd. Perhaps WordPress should stop showing post dates, page titles, and the number of comments for each post, because, after all, anyone who needs that info should know how to get it."

Post dates, page titles, number of comments, etc is all information that your average blogger will use regularly. Again, post,page,category ID numbers are never needed unless developing a theme/plugin or if a theme/plugin needs it and didn't supply the title/name dynamically for you.

This issue has been brought up over and over in trac for a very long time as well as recently, and has consistently been shot down by the core committers.

Removing it was a mistake, and leaving it out is just laziness.
It's not laziness, as the patch for it has been submitted numerous times. All a core committer had to do was commit it.
