Feedback is important but such a major change does not
Your example is somewhat misleading. Cutting an hour from the school day is to reduce the time that the students are in a controlled environment being taught, which would make an obvious impact to what, and how much, the students learn.
Homework, on the other hand, is just a matter of testing the students, not teaching. Arbiter mentioned a few studies that suggest that homework " does little to increase understanding and comprehension outside the classroom". And from personal experience, not doing my homework never held me back.
