Whilst many organisations are accepting that WFH is possible (and preferable for some job types) I suspect the pressure will be on the system to return mostly "as was" so that schools can provide their function as state supplied childcare. Thus ignoring any arguments over what may be possible educationally.

Certainly, many of the people I know who were/are keenest to return to their place of work are those that found balancing WFH with entertaining the kids difficult.

I would hope that within that remit of childcare the schools can then be more imaginative with what that might look like in terms of a school day - for example, more cross-subject projects, etc. However, it will remain the case that activity outside of those hours (sports, clubs, reading, etc) is just as important as what is done during - and it is this latter point which is often ignored by parents when they blame teachers for all their children's foibles.
