Heres one...... If you have a current transformer metered service ahead of the service disconnect and you use the neutral(or grounded conductor) to bond the metallic cabinet enclosing the current transformers, and you have a rigid nipple between the CT cabinet and the service disconnect which is bonded correctly and you have your main bonding jumper installed in your service disconnect as you should, would the neutral current thatwillflow on the rigid nipple be considered objectionable current by the NEC?

p.s. also think of the rules for a separately derived system as it applys to objectionable current.
