Currently every scope shares the same default configuration:

However sometimes we might need to allow "other" field(or other fields---cookie/css/img/plugin/XHR/scripts/frame) by default in the specified "_.A.com" domain scope,
while keep it declined in _other* scope.

This feature described is especially useful for some video sites(let's say youku.com), where video stream CDN servers are called directly by their IP address, which is of enourmeous quantity:

Something like

youku.com --- main domain
ykimg.com --- domain used for static image resource
123.132.123.132(an IP adress) --- a specific CDN address for the current video stream
