I tend to agree; if we're telling users "there's some drafting and we do what the drafting said as of XXX", then there's similar value in telling users "there's some drafting and we do not do what the drafting said as of XXX" (for example, as the issue is resolved, it tells us that we can convert it into a No instead of an Unknown).
