The explicit reason for its deletion is that a category intended to contain (indirectly) all the pages on the wiki is inherently meaningless. It has no reason to exist, since it does not organize pages in any meaningful way, so is just a maintenance burden.

You can find a list of all the categories with Special:AllPages. They do not appear as a tree, but that's more a technical limitation of Special:CategoryTree, which is unable to just list all the categories on the wiki as a tree, than it is a problem with not having a top-level category.

"Browse" is also a very strange choice, such a category would be better named "Contents".
