A and C:
What we are seeing above with all this talk of patches is a metalcentric view to load transfer and an assumption that the " glue" joint is weaker than the original structure, this is simply untrue, the "glue" or more correctly resin IS exactly the same as the original structure and so correctly installed will react exactly like the original structure. Therefore no additional patches or plates are required as long as a sufficient scarff area is avalable.
Why shouldn't it bother me that there's no continuous carbon fiber running through/across the new joint?
