The bigger context is this: jamf makes software to help manage fleets of Macs, by providing abilities such as deploying a package to a group of Macs. It's quite good and IIRC Apple uses it for configuration management. If a vendor gives you a normal package, as Java once was, it was fairly easy to deploy.
Contrast deploying the JRE with a simple package vs deploying it on Windows, which usually required an ever-evolving set of hacks to extract MSIs from the installer and install it in an automated fashion without installing bloatware, having it sit in the taskbar, auto-updating (which is a no-no in an enterprise environment), etc.
Now, thanks to this change, people on the Mac side will get to experience all the joys of deploying the JRE on Windows.
For what it's worth, the installer app contains a .pkg for the JRE that you can install by the normal methods. OTOH, the Flash installer used to contain a normal package, but no longer does.
