and Mynewlicense yields. this is exactly what i said. Mynewlicense is
in effect a disjunction of various licenses: either Mynewlicense or
AGPLv3. at no point does it apply in parallel to the AGPLv3.

that clause is the whole reason the terms of Mynewlicense aren't
passed down the line to derivative works, but the AGPL terms are. it's
also the whole reason why _both_ GPL and AGPL need section 13. how is
that irrelevant?

i should have been more explicit when i said that both AGPL and GPL
needed to work together for compatibility to work. i was only
referring to *their* compatibility as it exists.

this is a good argument against the part where I went full literalist
interpreting the copyleft clause. those licenses don't need extra
permission because they've been traditionally understood as subsets of
what the GPL already demands. this is what the Software Freedom Law
Center has to say on the matter:
