This was already discussed in your own thread SysExtension framework mere two days ago.

Let me repeat it once more:

With these frameworks, the code creating instances don't need hard-coded names of classes. It lets a framework to find the right subclass based on some parameters.

Here you can find more information about SysExtension framework, including an example: https://community.dynamics.com/blogs/post/?postid=31bbc085-ba95-4f75-a82a-de52a867005a.

It's also important to mention that if you use a switch statement, such code can't be extended. But these frameworks do support extensibility, because you'll simply create a new and you don't have to change the method creating instances.
