Thanks Corey. I think this would make for a perfect talking point during our (Apache Solr) monthly dev community meetup. It happens on the third Wednesday of each month at 12 PM EST. Next one is on 05/20.
If you are able to make it to the meeting, I'll also add this on the agenda once the meeting notes are out (likely some time this week). I am excited to discuss this further!
