i worked on a graal integration with pants jvm tools during twitter's hackweek last week and i managed to clean it up a bit and it's not "done" yet but getting the same perf as a warm nailgunned scalafmt without the nailgun with no optimization by invoking native images with zero startup time is enough for me to stick with it at least and actually try to benchmark it: https://github.com/pantsbuild/pants/pull/6893. gotta love how adding a new jvm tool execution backend as well as adding async execution for parallelism is <400 lines of code lol
