Who is the target audience here? And who exactly is paying for this? Researchers who care about open access can and do already upload their work to arxiv and/ or scihub in addition to publishing their work in formal venues.
Politicians who want to require open access journals for govt funded work? Researchers who need “gold plated name” journals for tenure? Just speculation.
Not this one. The open access requirements tend to be a year's delay and then it's open access at no cost.
