Speaking of patent I don’t know what regulation is, but when one looks at other scales, it can be considered almost every manufacturer develops his Kadee style (and Kadee compatible) coupler. Thus one could imagine the same for Z....
I believe patent law is about the same worldwide. The patent assignee has 20 years exclusive rights to the design, with the possibility of extending that time by updating the patent or lack of the ability to execute the patented item with existing technology. The patent holder can license the patent to others or keep it for themselves. Kadee did the former and MTL the later.
But one of the features AZL could incorporate (or keep available) on their locos and rolling stock would be at every end a chassis mounted socket allowing modeller just to screw a MTL #905 coupler in place. That would definitly be a plus for overall excellent AZL rolling stock and motive power.
I agree that a body mount hole, or even a drilling dimple would be desirable. I would be happy if all manufacturers would agree on a common, easy to use coupler box so we wouldn't have to mess Märklin's hot melt closure or molded on couplers.
I find the magne-matic® couplers a clever solutions but a bit awkward for execution with all those magnets/electromagnets. What I would put on my wish list would be for some future road switcher or especially a yard switcher to have an electronically controlled coupler. It could be built with a solenoid like the ones used in the Rokuhan turnouts. Full control would require DCC, but could probably be controlled in DC by cycling the polarity of the power.
Charlie I think you're selling passenger operations short. At your SLC station, UP assembled and split various City trains and SP would turn around their Overland. Railroads would have various rules that required working passenger cars: kitchen rear-facing (or front facing), vestibules facing rear, compartments always facing the ocean (SP), domes short end forward (WP) or sleeper aisles facing parallel tracks (various). All this requiring operations with al least a good "Y". Even today Amtrak does split/mergers of the Empire Builder in Spokane. IMHO there is considerable opportunity of passenger operations even before thinking about servicing tracks.
