The BG can't see the Golden Path. It's one of their major failings and the reason why they wanted their Kwisatz Haderach in the first place, to lead them with fully sighted prescience.
As with every report preceding this one, we must address the Lord Leto’s prescience. There is no doubt that his ability to predict future events, an oracular ability much more powerful than that of any ancestor, is still the mainstay of his political control.
We do not defy it!
It is our belief that he knows every important action we take far in advance of the event. We guide ourselves, therefore, by the rule that we will not knowingly threaten either his person or such of his grand plan as we can discern. Our address to him will continue to be:
“Tell us if we threaten you that we may desist.”
And:
“Tell us of your grand plan that we may help.”
He has provided no new answers to either question during this period.
God Emperor of Dune
It's not entirely clear whether the Golden Path plan (e.g. the need to push humanity down a specific set of pre-determined outcomes to prevent their extinction) ended with 'the scattering' or with the birth of Siona and her unique prescience-resistant genes, but there was very little scope for the Bene Gesserit to need to support his plans after the God Emperor died.
