I think this is good enough for now, and we can think about how to make this better in a follow-up. (My cause for concern is that with subsections via symbols implemented, some object files could end up with a sizeable number of sections, so even copying all the pointers over could have a non-trivial cost.)
With the order file diff, we'll need to copy over all symbols as well, so I think I'll switch this to use a global objectFiles vector
