Typz added a comment.
It is explicitly documented in google style guide:
https://google.github.io/styleguide/cppguide.html#Loops_and_Switch_Statements :
> case blocks in switch statements can have curly braces or not, depending on

> case 1: {

So IMHO we cannot just change the current (or default) behaviour.
