There's only a single longitude line within a time zone that meets the criteria of sunrise and sunset occurring at the same time. It's silly to use that as the deciding logic for whether to keep DST or non DST when eliminating the transition.

Unfortunately that will split the vote. If 60% favor eliminating the transition, that probably means 30% prefer keeping DST and 30% prefer eliminating it. Those will lose out to the 40% who prefer keeping things as they are.
