I agree with you, Hubert. Third party code should pull in any headers
that they need but they shouldn't need to have inside knowledge of what
those headers use. After all, it's not like we actually save
anything. If the header needs something, someone needs to pull it in.
Why not take responsibility for its own requirements?
