I believe a major part of the issue is that attempting to answer the question "Will allowing mutating operation *X* on object/type/float/int/etc create any interpreter stability or security problems?" is awfully close to trying to prove a negative. Certainly, at least some of the "generic" operations involving types include additional sanity checks that are bypassed for the builtin types. One specific example I can think of is that object.__hash__ is special cased in a few places due to the way its definition interacts with the definition of comparison operations. Allowing changes to the contents of object's tp_hash slot could lead to much weirdness when it came to __hash__ inheritance.
