There is a bit of leap in the logic flow here, in that the current state alone does not justify such a removal of the code that is not hurting anybody. I thought I did the necessary homework the last time to help you update the proposed log message for this step with necessary due diligence, like when we stopped producing it ourselves. The lack of third-party tools still relying on the code we are removing here is not something we can prove easily, so documenting that we go by faith there would not hurt, either.
