That sounds fine, you have an option that let the user overwrites the
warning though right (if cleaning only part B was really what was wanted)?

I think I would go for this one but only if you provide an option to
disable the smart behaviour and let the developers who know what they
are doing be in control. If you don't provide the option, or until you
do, I would prefer for the tools to error out asking me to be more
specific than wrong guessing what I might be trying to do (and e.g
cleaning out that webkit part that takes another day to rebuild)
