We shouldn't be naming things to because we want a particular name to be displayed on a particular rendering of the map: we should be naming things correctly, and leave it up to developers of things like mobile apps to figure out how to better display the information contained within. That a mobile app can't distinguish or recognize "alt_name" isn't really our problem, and it shouldn't be our goal to accommodate them.

The more I think about it the more I convince myself I was wrong when I said "neither [name] really has precedence over the other". It seems clear to me now that "8 Avenue" has precedence: there are no "Stephen Avenue" mailing addresses, the legal address of every building along the street is "8 Avenue SW/SE", etc.

I did add a node to the map a while ago marking Stephen Avenue as a historic site, so it's not as though it isn't already on there separately from the road itself. And it isn't the road that is significant as a "tourist attraction" as it is the streetscape of the old buildings, shops, etc.
