GPL3, Section 7, optional terms a-f are nothing like the extra
restriction of the AGPL.

The extra restrictions of the AGPL are part of the AGPL alone, and as
far I as I can see, GPL3 makes no explicit recognition that such terms
could be permanent according to the GPL3.

GPL3, 10 says: "If the Program as you received it, or any part of it,
contains a notice stating that it is governed by this License along with
a term that is a further restriction, you may remove that term."

However, I guess, removal of that AGPL term is without effect if the
work stays combined with the AGPL work, or rather, would breach the AGPL.
