I think that would be a good change.

At the risk of sounding like a broken record:

- Currently, if someone does not mention they have used AI, we don't know whether they actually didn't use AI (ok), or if they did use AI but hadn't read and complied with the AI policy (not ok).
- With this greeter change, the ambiguity remains: we don't know whether they actually didn't use AI (ok), or if they did use AI but hadn't read and complied with the greeter message (not ok).

> Even if we ask people to type "Yes, I have read the AI policy and agree to follow it.", it won't guarantee that they actually will. It is bound to remain an honor-system policy.

It doesn't prevent malice but it would help honest contributors avoid making an inadvertent policy violation.
