It's about abusing locals, which are not even given that they'll modify this dict.
Note that class bodies are a special case: as of PEP 3115, it's possible for a class body's locals to be a non-dictionary object, so it makes no sense to make a class body's locals() or f_locals return some *other* object.
Meanwhile, as a practicality-beats-purity matter, you're going to run into compatibility problems with a fair number of libraries in the field (including Zope and Twisted, and anything using them) if you *don't* support locals() modification in class bodies. (Those other libraries don't use non-string keys like AddOns does, but they *do* depend on modifying a class body's frame locals.)
