Honestly-- ask yourself this. How much goodwill would it burn? Is it worth it?
If you truly feel that you need to signal to SOMEONE that you're aware of this practice... I'd approach it light-heartedly with a laugh...
Well, I guess that's one way to 'demonstrate academic progress' in the students who are already highly capable at the start of the school year....It's not as though this is a transcript that colleges are going to look at. Bear that in mind. JMO, but I'd not make this kind of thing my personal hill to die on. There's a lot more nonsense than this to spend energy on, but that's just my experience. It's possible that for you, it matters that much.
