I don't think that this is a good approach. Imho classes should have 
minimal dependencies and the use of a "standardized use set" would 
encourage people to couple classes again. This makes every refactoring 
very hard as every dependency has to be considered.

Use the imports where it's necessary. My rule of thumb is something like 
"is something used more then twice, then import", "is something from the 
same namespace used more then twice, import the namespace". Maybe such 
an advice could go into the CGL.

Thanks for bringing up this topic as many have maybe wondered about that.
