The reasons are:
1) Type feedback vectors are not shared between different native contexts and
   therefore the IC handler created for one native context will not be reused
   in other native context.
2) Access rights revocation is not supported at all, therefore given (1) once
   we pass the access check we don't have to check access rights again.
