I don't doubt that is the expectation, but I think they are underestimating how much we arrange our daily life by the sunlight. While in the summer months the longer day length makes the concept DST working - in a sense the DST time change is a hack that somewhat works, the things get more tough in the winter, where morning brightness is very important. And also in the summer, at least for me, it is an illusion. Because the one hard constraint is, when it gets dark and cool enough to sleep. And here in Germany, that means around midnight, when DST is active. And that of course pushes the rest of my day cycle around in consequence.
