Gilles Sadowski commented on MATH-1695:
---------------------------------------

bq. Vector API

Doesn't it imply targeting Java 20+ ?
Commons Math is at Java 8.

bq. does the legacy package need to go through "modularization" first?

Ideally, yes.
Practically, yes too: I guess that we must define new _interfaces_, to be 
implemented in different "modules", potentially with different JDK 
requirements, so that environments stuck with old JDK versions can still 
upgrade the library (but won't get the improved performance).

>          Issue Type: Improvement
>          Components: legacy
>            Reporter: James Howe
>            Priority: Major

> Is this blocked by spinning out a new Commons-Linear or similar?
