Does the stark prover support (perfect)zero knowledge?

[XuyangSong]

Can I use the stark-platinum-prover in situations that need to hide private data?

According to winterfell Implement perfect zero-knowledge #9, it hasn't implemented the feature yet.

From an article, it mentioned:

Currently, none of the generally available provers (such as StarkWare's SHARP and Stone, or Lambdaclass' lambdaworks) guarantee that data is not leaked in their proofs.
