In my circle, there are several parents with kids in school, and so far I haven't heard any major complaints about homework - the real issue is that schools are still figuring out how to organize all this.
The main thing to understand is that increasing the minimum workload doesn't necessarily mean adding new subjects or hours to the schedule. A school can simply go deeper into existing subjects, add electives, or shift time toward practice instead of extra theoretical material. There could be more homework, there could be less - that depends on the school and teachers. Some places will redo their schedule, some will cram everything into one schedule, some will add Saturday classes.
My tip: if your school announces changes, try talking to the teachers and administration. Often they're willing to discuss how not to overload students with extra work at home, especially since that's on trend in education right now.
