Interesting. We added a ssrMode: true to AC which simply ignores forceFetch to get around this problem originally.

I don't recall if we had an idea at the time of use cases where people might validly want to force fetch in SSR (and thus not set the option). Probably not huh? If so, we should remove ssrMode as an option to AC (and make sure the angular SSR works the same way).
