Well, that is a good example actually. Of course you don't want to lose the ability to right-click, but there are also various web apps that override the right-click menu for legitimate reasons. Two examples that come to mind are Jupyter Lab and Outlook 365, both of which use a custom context menu. Disabling the context menu setting presumably breaks this functionality.
My idiot bank disables right-clicking, and I'd be all over the option to disable right-click hijacking, but yup I also use a web app that overloads right-clicks in a sane and appropriate manner.
