As full-time, undisrupted education in school is not going to be available - or will only be available to a lucky few - are you saying you would prefer ad-hoc, unplanned bubble and school closures due to staff sickness, Covid outbreaks or local lockdowns due to community spikes, to a planned delivery of blended learning that mixes part-time school attendance with part time home schooling?
Gaps will become wider in the 'open full time, close randomly and hope for the best' plan, because community infection is highest where the most disadvantaged are congregated - you can see it in the communities tha have had increased restrictions so far.
Planned part time in school and part time high quality remote learning for all, with provision of laptops to the most disadvantaged (or even a specific socially distanced self-study facility within or outside the school for those children) would, IMO, close the gaps more successfully.
