It’s in a separate dev stream right now, so not in quite yet. I’m having QA go over the changes week, and still working on cleaning things up and testing. It will make it to once we are confident that current standard behavior is unaffected and perf is minimally impacted.

The PR 1773 has some comments I made recently about some code I had questions on, you could add comments there as well. Ideally once code is in you could commit PRs to fix/add features. However I’m open to suggestions. It may be a few weeks until that point.

Ok, I’ll try to add comments there as soon as I can. I will also report bugs that I noticed through Answerhub.
