Review comment:
We will not include this on the current release branches right? IIRC the
return value change could also break a compiled java code since the JVM record
the return value type in the final generated method name for linking.

Review comment:
There is no IS.Evolving for IA.Public classes, it should always be
IS.Stable implicitly, so we do not add IS annotation for IA.Public classes.
