Of course, it is not about the fatality. It is an example to point out that a rarely used feature does not mean it is not important. Another example is Google search remove the ability to perform exact text search such as "some phrase I found important to search". Maybe based on statistic, it was 20% of user using that, 80% of users does not rely on this feature. The logic is saying messing up 20% of user is not a problem. We are serving the 80% of users pretty great. The current paradigm of UX design for providing "good default" to serve 80% of users and removing customization to screw 20% of advanced user makes me pretty helpless for using modern app. That's why I prefer cli nowadays for the flexibility of those software.
