Just for my understanding, the current implementation of [secondary super cache lookup in Graal](https://github.com/oracle/graal/blob/0a471fc329ea2c8c18c05f9d83347dc1199c3ad9/compiler/src/jdk.graal.compiler/src/jdk/graal/compiler/hotspot/replacements/InstanceOfSnippets.java#L169) will continue to work until we get around to doing the port right?
