The experimental warning will be withdrawn when there’s confidence among 
committers that the feature always does the right thing with your data. 

The algorithm SEEMS safe (with the caveats Blake mentioned), and people DO use 
it in production, we just want you to be aware that we’re not as confident in 
its safety as we are for the more mature database features.
