@youronlyone Ok, I think I found what I'm looking for: #CCPlus. A particular CC license with additional permissions granted, or agreement, on top of.
I want a license:
1. that is #ShareAlike / #Copyleft
2. but without the Attribution requirement
3. and without the State Changes requirement
4. and is applicable to every derivative
Under CCPlus:
1. License the work under #CCBYSA first
2. Then state the additional permissions, like #NoAttribution and #NoStateChanges
However, I don't think #4 is posssible? I think it is contradictory, since the license is CC-BY-SA and the “Plus” is not, it's only a waiver of additional rights. But, then again, it is also a separate agreement, so, shouldn't it be possible if #4 is stated?
See: https://wiki.creativecommons.org/wiki/CCPlus
n.b. This is for non-software, or #literature, works. There are situations where I personally don't think an attribution is needed, and stating changes is too much. But, it is beneficial for the community that any derivative are under the same #license.
In any case, in software, a close equivalent is #MIT0 (no attribution) and #MPL2 (no state changes).
