The only use case I can think of would be as a migration mechanism; for languages that currently run on the JVM and produce many classes, it might be an easy first step to use ACs instead of refactoring in method handles across their runtimes. But that's just a theoretical possibility. Glad to hear that perm gen will eventually go away. Thanks for the clarification.
