Considering how wide time zones are that is pretty much impossible to standardize on regardless of which clock you pick. Then it becomes a question of which cities you are going to prioritize, and I doubt any politician wants to start that conversation.

Plus, "solar noon" itself shifts by ~20 mins throughout the year due to the Earth's orbit.

With standard time you will still have the rough center of the time zone match with solar time with about +/- 30 minutes give or take on the sides. With DST it may well happen that no part of the timezone actually matches solar time since everything is essentially shifted 1 hour to the East.
