ArcPro 3.1.0 makes it easy for the non-technical to install additional python modules through the Package Manger. Love it! Currently the version of shapely that the package manager can install is 1.8.4.
Version 2.0.1 is available and has better support for precision and no doubt other functionality.
My idea is that ESRI makes it a priority to support shapely 2.0.1 through the Package Manager.
Yes I know it can be installed manually but that's a route that will put off non-technical users.
