I'm not sure we should do this, can a ScriptSourceCode be transferred across
threads?

ScriptSourceCode is not transferrable unfortunately.

Gleb and I talked in person, agreed that we'll pass this object through for
MainThreadWorklet and the ThreadedWorkletGlobalScopeProxy will grab the
components to transfer across to the thread.
