Yes, me too.
Raffaello, as an experiment you could develop such classes as primitive classes compiled against recent builds of Valhalla.
I would caution against unduly biasing towards "business applications”, as I think with primitive classes and other possible features Java can become a better platform for scientific or engineering purposes.
As an example we are making progress with the Vector API and in the panama-vector repo we have integrated with code of Intel’s Short Vector Math Library, which may open the possibility for it to be used by the auto-vectorizer too.
