I’ve read this announcement. Did you create a presentation? :)
I presented on this at TABconf last year. Or at least I prepared to...I can't remember if we covered it at the Socratic session.

Discussion
Socratic Seminar style: just highlights on the web page and an open discussion where questions are encouraged.
I haven't heard very much about it since then. It seems like a not-so-sexy infrastructure upgrade that most people will never even know is happening under the covers. One of the thousands of optimizations that makes lightning "just work". But super duper cool engineering for the nerds out there who dig this stuff. 🙂
