Review Comment:
I'd really rather not rely on the mutability of the `workerProps` field as
it makes its way though various stages (builder, instantiating embedded worker,
starting embedded worker). I'm also uncomfortable passing in a null
transformer--a no-op transformer would be cleaner, but also more verbose.
I'll give it a shot.
