Do subsystems need some kind of registration? If I run

./pants -ldebug --compile-rsc-worker-count=8 --process-execution-local-parallelism=8 --compile-rsc-execution-strategy=hermetic --no-compile-rsc-incremental --compile-rsc-workflow=rsc-and-zinc compile --cache-ignore examples/src/scala/org/pantsbuild/example/hello::

I get told:

No such options scope: rsc

when

RscCompile

tries to access

Rsc.global_instance()
