Some more details

Toronto and New York are in the same time zone, yet they are both present. I could cite a bunch of examples.

It was a bit of a tongue-in-cheek joke: Montreal *used* to be present in the tzdata files, as a distinct entity. It got turned into an alias, which caused a huge controversy... But I do think that configuring timezones based on geography assumes a certain level of knowledge that may not be uniformly available. We assume too much, and more citites would be better, not worse... Living outside of the city these days just shows me how so many things are geared towards big cities, at the detriment of rural communities or smaller areas. It's something we often forget about...
