      "--tag: Tag for the version.",
      "[VERSION-SPECS]: Version shorthand `<version-id>@<percentage>`; use `100%` to assign all traffic to that version.",
      "Prerequisite: Secret bulk input must be JSON to request deletions with `null`; `.env` format does not support deletion.",
      "Deletion applies to the new Worker version; deploy that version with `wrangler versions deploy` to apply the changes to production traffic.",
      "Docs conflict: The current Wrangler command docs describe `versions secret bulk` as creating or updating a secret and do not document null-based deletion, while the v4.148.0 release note says it supports deletion. Follow the release note for that changed behavior."
