   @FMorschel I had to do a double take, but isn't this just .new() everywhere?
   I.e. this works today without any changes

   import 'package:flutter/material.dart';
   
   void main() {
     const CarouselScrollPhysics carousel = .new();
     const FixedExtentScrollPhysics fixed = .new(parent: null);
   }

   You want named factories on ScrollPhysics itself?

   Yes exactly. Because that way we can use them in the Widget tree like at Listand similar.
