Hi Bertrand,

> I think that an extension can trigger it without shrinking the relation

I think you are right here and I missed that case. Not sure if any extension
really did it or not.

So my earlier mail was too strong. Core can't reach it, but an
extension can. It might be worth saying that in the commit message.

Thanks,
Shihao
