No, it's not an artifact zone.tab was never intended to be a definitive delination of sub-country regions, and it does not have that role now, either.
Kansas is split into two time zones, for example, but we don't have two entries for it in zone.tab -- the people in Kansas can use America/Denver or America/Chicago as appropriate. The situation for Indiana is similar: people in (say) Gary can use America/Chicago.
You're being unnecessarily aggressive when all I was doing was pointing out two facts: A) the description for America/Phoenix said "Arizona" B) there was no indication in America/Denver that it did not apply to parts of Arizona. I could go back further and point out that (back when the names were self-explanatory) they were called "US/Arizona" (again, implying in the absence of anything else that it would be all of arizona) and "Navajo"
