For expository purposes it might still be useful to have actual ES versions of the default pseudocode sections of the internal methods somewhere. This could either be via a non-normative addendum to the spec, or left up to the community to provide outside the spec. The latter option might be better since it could be updated independent of the spec in case of any bugs found.
