Do you mean that you use subclasses to register selectors that will not be trapped? 
Why is is better than a collection on the object?

I not understand your question.
For example you want to make message #asString meta. You can implement it directly in class GHStandartMetaMessages:
GHStandartMetaMessages>>asString
"here there is instance variable ghost which you can use for implementation"
^'string presentation for ghost'

Now if you will define your proxy with standart meta level #asString will be not intercepted and instead GHStandartMetaMessages>>asString will be executed with ghost. 

In previous version you would add #asString to special map:
initializeMetaLevel
"many many other mappings here and new one"
notInterceptedMessages at: #asString put: #handleAsStringFor:
