Ok. I suppose these methods could eventually be moved to `java.lang.Math` or some other `java.lang` class, when the VectorAPI goes out of incubator mode?

I feel like these saturating operations, and also the unsigned ops could find a more wider use, away from (explicit) vector usage. For example, the saturating operations are nice because they prevent overflows, and in some cases that would be very nice to have readily available.
