Please clarify.  Give a mockup of what you mean, for instance.  I'm not sure I
understand.  Are you suggesting that it should be possible to add additional
category namespaces?  So that [[Foo:Bar]] would include a list of pages
including the text "[[Foo:Bar]]", instead of [[Foo:Bar]] linking to it?

More like having a link below the "Category : Whatever Category" that says
"Namespace : Whatever Namespace" that links to a page that lists all or a
pagenated list of all the pages that are within that Namespace. Similar to
[[Special:Prefixlist/Namespace Name:]] only without the search form, similar in
appearance to, and editable like [[:Category:Category Name]].

... or perhaps all Namespaces could have an implicit Category named
[[:Category:Namespace Name]] that is implicitly included in all pages under that
Namespace.

So basically you want a link to [[Special:Allpages/Wikipedia:]] at the bottom of
[[Wikipedia:Neutral point of view]], for instance?  Except you want the editable
summary like on category pages.  Hmm.  This seems like a somewhat niche request.

Yes, exactly. Could make it easier for people to find stuff.
