It is not clear why we need 4 new maps? Can you list the different cases

functions and how their maps differ?
SLOPPY_FUNCTION_MAP and SLOPPY_FUNCTION_WITHOUT_PROTOTYPE_MAP install
caller/arguments accessors as own properties, which is forbidden. The strict
variants of these install the poisoned accessors as own properties, which is
also forbidden. For legacy syntactic forms, this behaviour is still needed

so it seems that you need the extra maps.
If the global maps weren't set up, and the accessors were added during
function
instantiation, you'd still end up with new maps implicitly.
