Correct, that's just for the header. Given the prominence of categories in the header, we didn't feel it was necessary to show it there given that most main pages just use Category:Browse.

For wiki names in the header, there are two big reasons: community flexibility and visual accessibility.

Additional flexibility comes from two things:


 * 1) Wikis that might want to use a different nickname in their wordmark vs their sitename now have the freedom to do that. The wordmark can say whatever it wants, while the sitename can appear as the standard text.
 * 2) Historically, wikis have had to rely on their wordmark to communicate that they are a wiki but now they have more creative freedom in that space.

Accessibility is for people who may be more visually impaired. Some designs are really intricate, use unique fonts, have smaller text under a logo, etc. Putting the name to the right of the wordmark ensures that as many readers as possible see what the name of the wiki is.
