The block settings come up automatically when using the full-site editor, so it's not really taking away from the editor real estate to include information on what's included in a pro version. Yes it might be frustrating to see an option for a feature that you can't actually use yet, but at least you now know it exists in the pro version if needed for your use case. It's not globally displayed like admin notices often are - so might be a little harsh to compare the two :)
