I don't know about unbundling. But it wouldn't be a surprise if at least relatively motivated students being individually homeschooled for a while--even given remote work challenges--by wealthy, educated parents did pretty well. (Whether or not on standardized tests is perhaps less certain.) Whereas kids in less good home environments aren't likely to.
Schools are providing bundles of tools: computers, textbooks, teaching, videos, testing, classrooms, group work, childcare, 'nutrition services,' libraries, etc.
The crisis takes away the classrooms and exposes the tools to parents. And for some people the classroom made little difference, or held them back.
By fall, I think you'll have people asking whether school boards shouldn't just offer the tools. Let people pick and choose their own arrangement of teaching, video, testing and groupwork. (This would let wealthier parents recover some of the amount spent on unproductive childcare, and put it into learning and socialization.)
