Posting a link to Eric Hanson's post on this issue on the Julia Discourse. The concerns raised about unexpected behavior, bugs, and non-composability need to be considered carefully. Data science workflows grow to use multiple packages for various functionality over time. It would be good to avoid unpredictability arising from changing Base behavior.
