We did with some. Although I don't recall the exact specifics but there were improvements we were able to make with GC tuning and switching from CMS to G1. We were on old version of Cassandra for our most problematic cluster - and it was our last cluster to migrate to Scylla so we didn't really do much to explore the problem space of JVM tuning when we were already moving away from JVM already.

Supposedly this is a nearly "solved problem" but I am very curious to hear real world use cases and whether it truly works or not.
