I agree and the requirement for an exact placement of attribution is not very friendly to derivate works either. I don’t think that section 7 of AGPL allow adding anything other than the exact terms in section 7 and it has a clause that allow removing non-permissive additions to the AGPL, but I’ve sent an e-mail to FSF asking what their position is. I would be very concerned picking AGPL as a license for my projects, if section 7 allow adding clauses like that. Anyhow the clauses were added in this commit, so anything prior to 7.3.0 is normal AGPL.
