rHG6e81446bf1d9: share: move share safe functionality out of experimental
rHG4b0192f592cf: share: move share safe functionality out of experimental
Summary

The share-safe functionality is complete and all configuration options are
implemented. The behavior is well discussed on mailing list and in reviews.

Let's unmark this as experimental to solve a chichen and egg issue.
