And they’d need to tell you when those hours start and end. In practice it would be a random mishmash of DST transitions on a per-service basis.
And it’s not like you’re going to get tons of daylight after work or anything. The sun will go down at 17:30 instead of 16:30, but if you have a 45 minute commute and want to get to work at 8:30, you’ll have to be out the door at 7:45, 30 minutes before the sun comes up.

Notice how the DST transition keeps sunrise relatively constant? That’s actually a decent feature, particularly for people like me (and people with young children) who tend to get up with the sun.
