That's my impression -- the point of Wikispore is to allow extension + policy/scope experiments and effective history-preserving page-transfer once new wikis are launched.   

Extensive examples of pages intended to go on new wikis isn't quite the current scope of Meta (though anything can be described in meta terms, and I personally am fine with Meta being an umbrella for all other things, I know not everyone shares that), and it has plenty of active uses + user groups which make it harder to experiment with wiki-wide features.
