(I'm the author of this last repo.) You are correct that these no longer apply to the most recent Node versions. Crankshaft is still being used in Node <8.3.0.

(I'm the author of this last repo.) You are correct that these no longer apply to the most recent Node versions. Crankshaft is still being used in Node <8.3.0. Crankshaft got totally disabled starting from V8 5.9. Node 8.2.1 uses V8 5.8.283.41, Node 8.3.0 uses V8 6.0.286.52. I'm pretty sure there is still a big number of projects running on Node <= 8.3.0. I'll make it clear in this project README though, whenever I find time. :)
