Craig from Citus here. In situations where compliance is an issue you would absolutely want to obfuscate the data. You could do this after the fact in a few ways, but have a data set that imitates the distribution and size of your production database even in those cases is still useful. Given only the engineers with production access would be the ones forking before they handed it off they could put the right tooling in place to obfuscate.
All that said it's helpful feedback and something we could definitely look at building more into the product.
