By 'type', do you mean the one and one objected named 'type or the class 
being defined?  To be really clear, will the following change?

 >>> class C: pass

 >>> type(C.__dict__)
<class 'mappingproxy'>

If the proposal only affects (slows) the class definition process, and 
then only minimally, and has no effect on class use, then +1 on being 
able to avoid metaclass and prepare for its most common current usage.
