1) Yes. Working on it. (You can already partially do this e.g. ?score=90)

2) Yes. You will see these radically improve over the next few weeks. As stated on the scorecard itself they are a work in progress. You have to consider that overnight we intentionally exposed tens of thousands of warning messages across thousands of plugins, so there will be false positive, false negatives, and severity tweaks as we gather feedback from the community. But I expect these to get sorted out fairly quickly!
