But someone could use it on a derivative of a work I release under
CC-BY-SA without opting in.
For instance, if I make map tiles under CC-BY-SA, someone could make
derivative map tiles under CC-BY-SA with the opt in, and then I'd need
to get a lawyer to check whether or not I could use those derivative
tiles in an iPhone app?
In any case, I looked into the "anti-tivoization" clause in GPLv3, and
it seems to me like it's built around the requirement to distribute
source. But CC-BY-SA does not have a requirement to distribute

The problem is that I'd need to go through the trouble of figuring out
whether or not you correctly understand yourself.

Yeah, well, that's the beauty of CC-BY-SA. You don't have to worry
about all that crap. You just release the derivative work under
