Do you think it's feasible NOT to add this option, but make it a default instead? It looks safe enough, at least for "navigation" and "pagination_only" strategies. Maybe it's fine for "full" as well. We might need to do some experiment to ensure it's safe though.

After some analysis, it turns out we can enabled crawling products outside of the domain by default. I guess the ultimate switch by users here would be enabling the AllowOffsiteMiddleware in settings.
