When beans are stressed by weed competition and heavy brows pressure they don't produce pods, regardless of type. Eagle beans are forage beans that put most of their energy into producing leaves rather than pods. That does mean they don't produce pods. The pods, and the seeds, are just smaller than in Ag beans. While Eagle makes claims about their specific beans, the benefits their varieties offer over others are small compared to two characteristics, they are RR and they are forage beans. They forage beans tolerate browse pressure much better than ag beans and the fact they are RR allows for easy post emergent weed control.
With more weeds becoming resistant to roundup, the RR feature has lost value over time in many areas. It just depends if you have weeds that laugh at glyphosate. Liberty is a new bean/herbicide combination that weeds have not yet become resistant. I don't know of any Liberty forage beans but perhaps others may weigh in.
My experience with eagle beans is documented on this thread with pics:

I will say that I planted Eagle beans to cover the summer stress period as I'm in zone 7a where summers matter for QDM. These indeterminate beans stayed green and attractive several weeks into our archery season which starts in early Oct. Deer ignore the pods in my area unless we have a mast crop failure. In that case, they eat everything we plant. Turkey, on the other hand, were on those little pods all fall and winter.
