Maybe we just have different experiences, but I've experienced a huge amount of friction trying to enable features that cost something resembling 0.5% of fleet performance, even when they provide massive benefits. 12% loss would be laughed out of the room.
I agree that this is an impressive feat. I also don't see why an equivalent for rust would be adopted.
