I think the point about schools is that the alternative (children not going to school) is generally worse for spread given the problems it generates for childcare (and knock on effects for parents, grandparents, etc).
(Only primary school experience for us though, I can see it being quite different at secondary and far different again for Y12/13.)
If schools were the primary transmission vector then I would have expected to see that represented in the spikes much more clearly. (That doesn't mean they aren't a lesser source of transmission, just not the primary site.)
