Proposal: Make destructive edits actually destructive in git repos

Codex CLI feels overly conservative about removing code. Even with explicit prompts like “delete X entirely; no placeholders/comments,” it often:

• Inserts placeholder comments (e.g., <!-- removed: … -->, // removed: …).
• Leaves commented‑out code instead of deleting it.
• Writes timestamped backup files on overwrite.

In git‑first workflows these safeguards create noisy diffs and stale breadcrumbs. Git already provides history/undo; the extra artifacts are detritus to be dealt with by the developer or by Codex in follow-up requests.

I figured I'd make a request here, because Codex (apparently) has really good defaults around git hygiene in its system prompt, wherein it generally won't start doing git operations like commits and pushes without being explicitly told to. As a result, addressing this in Codex feels appropriate.

Please either make this behavior configurable or relax it automatically when Codex is operating inside a git repo.
