In Mathematica versions prior to 11.2 or 11.3 (not sure at the moment) it was possible to select the default format type of new output cells via Preferences -> Evaluation. In particular, it was also possible to change it from StandardForm to TraditionalForm, which I personally like very much.

From the point of view of a package developer, TraditionalForm typesetting allows to make the output more visually appealing and close to what people see in books and papers. And it is also quite fun to develop TraditionalForm typesetting rules. I understand that sometimes it might be confusing to new users, but the StandardForm is often just too inconvenient to read, so I actually only use it to copy and paste expressions.

However, in more recent Mathematica versions this option was removed from the preferences and is now "hidden" in the Option Inspector. A new user not aware of the existence of TraditionalForm would now always see only the StandardForm output.

Does someone know why this happened? Were there perhaps some recent statements from WRI regarding the future of TraditionalForm? I truly hope that it is not going to become deprecated or something like that.

TraditionalForm isn't going anywhere. In fact, the new Wolfram Alpha Notebook Edition defaults to TraditionalForm output. As one the lead developers for typesetting, I can assure you nothing has been ripped out, and we continue to add TraditionalForm rules as appropriate. However, we enter more and more areas where there is no "traditional" formatting to imitate, so there aren't always special TraditionalForm rules.

I can't speak to specifically why this option was removed, but there has been a general move towards simplifying the preferences to the bare essentials and leave other options to the inspector for "power users" to use.

    $\begingroup$ Also, there was some evidence that a few users may have set this option accidentally and without understanding the full consequences, leading to questions being asked of tech support or on forums like this one. $\endgroup$ – John Fultz Nov 21 '19 at 5:23
