Let the children start later. Let the parents start later and have a shorter work day. Problem solved.
The only way I think you can make DST abolition make sense is if you say "well, I guess kids are going to be at school in the dark at 9AM in a bunch of places around the country". That's a coherent argument! But "parents and workplaces will just figure it out" is, I think, not.
What would actually happened would that that women and some guys would be penalized in the workplace and ... that would be it.
