User blog comment:Brandon Rhea/New Page and Article Headers: Official Release Date/@comment-11733175-20170522215450

Is this being used as an opportunity to unify the many different page header types? A notable example, particularly noticeable on central, is that the blog namespace does not make use of the new edit button area. Another is user profile pages.

From the point of view of developing wide-use scripts that modify the header in one way or another, having half a dozen different cases to handle for a single skin is a pain.
