Why @Provided instead of @Assisted?

This isn't really a bug as much as a design question. as far as i am aware @AutoFactory was designed as a more performant alternative to guices assisted-inject extension, so i am curious why in @AutoFactory you annotate all the parameters that you want to be injected whereas in guice you annotate all the parameters that should be explicitly passed (with @Assisted).

I have a (mild) preference for the @Assisted approach since
1. in my experience, there are are fewer @Assisted params than @Provided params
2. the provided params will often already have @Qualifier annotations applied to them, so adding @Provided adds more noise to the parameter declaration (plus raises unfortunate questions about annotation ordering)
