Design vs. engineering question

[sutcac]

One detail I really like is the multiple A35s attached to I joist blocks. Ever try to put 6-12 nails into the bottom cord of an I joist?

I haven't seen that done since the very early years of I-joists. Now you generally don't block on the perimeter (where the A35's generally are for shear transfer) you have a solid engineered rim joist for this and the nailing works just fine. Maybe it's just taking a while for this to migrate up the Alaska.
