Oops, I missed that part. -1 on it, like Dominik. I originally did not have an 
IDefaultLayer when I converted views to adapters and it caused a lot of 
headaches for people. It was thus added and we all agreed it was needed.

Your connotation assertion here is incorrect. The default layer stands for: 
"If the browser directive did not specify a layer, use the default layer." By 
default, the Basic and thus Rotterdam skin incorporate that layer, but others 
like Dominik and Garrett do not want to include that layer.
