Actually, that makes complete sense to me too. It would be very easy to use "operator_identifier", and simply clarify in the North America tagging wiki that the appropriate value is the primary reporting mark for Canada, US, and Mexico lines. I see no reason that wouldn't serve exactly the same use we were proposing, but be more widely applicable outside NA.
This may be a good topic to foward to the OpenRailwayMap list for input too - I'll do that now, thanks!
