I don't have a strong opinion on this. The value of --illegal-native-access is examined during startup so startup can fail if a bad value is specified. Here it is mid-flight when Unsafe initialises. The coin toss landed on printing a warning but it could equally fail. I jus didn't want code executing during startup to check configuration for something faraway in the jdk.unsupported module.
