Furthermore, on all the usual Java usages of switch / case, they work exactly the same in Groovy. So I don't see why we would not be allowed to use the same syntax, to ease the transition for Java developers.

because a Java switch/Case does not work like a Groovy switch/case. In Java a case can take only int compatible constants, in Groovy it can take expressions. In Java all cases share a scope, in Groovy each case has its own scope. In Groovy we call the isCase method, in Java it has to be a number we switch with. If we for example use a closure as case, then this might cause side effects. There are cases where we can let them behave the same and usually when using the java version you won't see a difference in Groovy besides the placement and logic of default.>
