I tend to try to cherry-pick the dependancies in case (1) too
unless they are functionally invasive. Any time you manually
adjust a patch, you increase the likelihood that later cherry
picks will also require manual work. So I always favour a clean
cherry-pick until the point the functional risk becomes
unacceptable in the context of testing the change I'm pulling
back.
With regards,
Daniel
