Is Stack Overflow Meta incorrectly configured?

Question

If I call the Auth "sites" API, then it shows Meta Stack Overflow as:

  "name": "Meta Stack Overflow",
  "logo_url": "http://sstatic.net/stackoverflowmeta/img/logo.png",
  "api_endpoint": "http://api.meta.stackoverflow.com",
  "site_url": "http://meta.stackoverflow.com",
  "description": "Q&A for the Stack Exchange engine powering these sites",
  "icon_url": "http://sstatic.net/stackoverflowmeta/img/apple-touch-icon.png",
  "state": "normal",
  "styling": {
    "link_color": "#3D3D3D",
    "tag_foreground_color": "#6F6F6F",
    "tag_background_color": "#E7E7E7"

Is the "normal" state incorrect here? Or is Stack Overflow a "special" case?

Answer 1

No, this is expected behavior, Meta Stack Overflow is indeed a special case - see the original Per-Site Metas announcement, specifically the last paragraph:

For now we are leaving meta.stackoverflow.com grandfathered in, as-is, with no changes; it’s still a standalone community with a standalone reputation system. We think Stack Overflow is large enough to justify this, and it just so happens that Stack Overflow is also the name of the company, too. Meta Stack Overflow will serve as the “National Capital” where we process feedback not just for Stack Overflow but for the core engine itself — while the smaller meta sites are akin to regional or state capitals.

I've submitted a follow up question Shouldn't you take the plunge and have a per-site Meta for Stack Overflow too in favor of meta.stackexchange.com? back then, and Jeff Atwoods answer indicates that this isn't going to change anytime soon, though still something they might reconsider in the future.
