I believe that Cinnamon was upgraded to a newer version recently.
you may want to discuss this with the Cinnamon devs instead. As you are aware of, that is a DE configuration since you make mention of it from a historical standpoint.
I don’t believe that it is particular to an operating system
Devs from the various DEs have been removing and adding functionalities for quite a while now. An example is the Gnome dev team. There is historical evidence that points to that fact itself within the confines of that particular DE (adding and removing).
I have no doubt it is the same with Cinnamon (adding and removing different functionalities).
Its important to understand the differences between a DE, which is a compilation of programs, that run over an OS.
A Desktop Environment is an intuitive way for yourself to interact with your computer using concepts which are similar to those used when you interact with the physical world, such as buttons and windows, and right-clicking for a menu of some sorts.
I hope this clears it up for you and was found helpful.
Again, you would have to go to the Cinnamon devs for this.
