I obviously didn't get the memo, neither did the proposed time zone map mention about the reasons for changes. So here is the big question: why each state are proposing their own time zone now? The proposed changes look like a mess to be honest.
I think it's unlikely that the map will be this complicated after some changes are actually adopted.
I live in the north and the concern about DST always makes me laugh - the relationship between the time and diurnal patterns is meaningless up here for at least a third of the year.
The first Google result for me implies that these are largely myths (https://www.forbes.com/sites/startswithabang/2018/03/05/the-...).

If we had a Federal government that actually knew WTF it was doing, your idea would make sense. You really think the Trump Administration could make sensible timezone policy decisions?
