Explicit permission can be useful to preemptively cut off some questions from well meaning people who, acting in good faith, might otherwise pester for clarification (no matter how silly / "obvious" it might otherwise be), or get agitated by misconstruing an all-banned list as being an overly verbose "no LLMs ever" overreach.

Many of us work or have worked in corporate settings where IT takes great pains to help detect and prevent data exfiltration, and have absolutely installed the corporate spyware to detect those kinds of actions when performed on their own closed source codebases. Others rely on the honor system - at least as far as you know - but still ban such actions out of copyright/trade secret concerns. If you're steeped deeply enough in that NDA-preserving culture, a reminder that you've switched contexts might help when common sense proves uncommon.

While nannying can be obnoxious, I'm not sure that having a document one can point to/link/cite, to allay any raised concerns, counts.
