Hmm, I'm actually surprised this is still around, and the rust package has long not been in the experimental directory in the release. I suspect this might have become a no-op, but in the meantime it definitely needs to go here 🙂 thanks for spotting this!

ah, I see, experimental = True just duplicates the pack creating another rust-experimental target, that downstream consumers can chose to use or not. So yeah, this is dead weight at the moment.
