I've never come across a device that supports permanent summer time. You can typically opt out of daylight saving time and stay in standard time, but you can't stay in summer time.

These devices will either need to pick the standard timezone of the timezone to the east and disable daylight saving time, or we will have to change the offset of every timezone in the US, or devices will need to add an explicit summer timezone.

I don't see how any of this is easier than staying on standard time and disabling daylight saving time, which every device that tells time that I've come across seems to support.

It's not easier, it's better because more people prefer having an extra hour of light in the evening to an extra hour of light in the morning.
