I think it is important to understand what this does and does not cover. This is “only the first part of Valhalla”. See e.g. a good summary at https://www.jvm-weekly.com/p/project-valhalla-explained-how-...

I agree, but this really is one of the most important and useful parts to land. Next is the null constraints. Generics will be useful, but not needed to get a large portion of the performance benefits.

With this finally integrated, we are also likely to start seeing pretty regular performance bumps for all things value related.
