Ah, thanks @dantheman. This has been one of my main questions since joining the platform. I was about to post the question myself but found this post and your comment first. So, off the cuff before I chase pointers to the roadmap...

1. Has this pruning started yet?
2. Is the idea to prune periodically, or a problematic block is identified?

I may find the answer from resources. But if you can shortcut the process so much the better. Cool.
