For me, sometimes but rarely.
IMO, Steve is more of a minimalist than me. I have carried two bi-pods with me in the field. More typically I will carry the BR bi-pod and a pair of shooting sticks. Your day pack can also be a good rest too.
The BR bi-pod is for sure my primary, but I will also carry the next size up if I think the terrain demands it.
If, I think that my primary posture will be seated, then I pull out the 25C and the stadium seat.
I try to pick the bi-pod for the type of hunting I do.
This is not a big deal if day hunting, but if you ar ein the mountains then, lessening weight can be a consideration.
