In answer to your question, the exceptions that you listed are the present day exceptions, but it is a list that is NOT limited to those purposes explicitly listed. See below.
Actually, I hesitated posting again here so as not to unnecessarily concern anybody. I came to the same conclusion you came to: no matter how its is transported, you better be transporting it in the car for a "lawful purpose".
I didn't post my thoughts because I did not want to suggest any possible ways to charge CCW; we have enough hassles. But, the "cat is out of the bag" so to speak. The point really needs to be stressed that we need to make sure non-cpl transport of handguns is for a "lawful purpose"
. The only point I think could be made is that lawful purposes are not limited to the examples given in the law, rather it says that lawful purposes includes the following, not that it is limited to the following:
750.231a Exceptions to MCL 750.227(2); definitions.
(b) "Lawful purpose" includes
(i) While en route to or from a hunting or target shooting area.
(ii) While transporting a pistol en route to or from his or her home or place of business and place of repair.
(iii) While moving goods from 1 place of abode or business to another place of abode or business.
(iv) While transporting a licensed pistol en route to or from a law enforcement agency or for the purpose of having a law enforcement official take possession of the weapon.
(v) While en route to or from his or her abode or place of business and a gun show or places of purchase or sale.
(vi) While en route to or from his or her abode to a public shooting facility or public land where discharge of firearms is permitted by law, rule, regulation, or local ordinance.
(vii) While en route to or from his or her abode to a private property location where the pistol is to be used as is permitted by law, rule, regulation, or local ordinance.
