People who have broad interests with no depth of knowledge have not identified (for themselves) where their value lies.

I would imagine that this type of engineer needs to be carefully managed to stay on tasks that add business-value.

People whose value lies in coordination often need to dabble in multiple fields. Think of a technical artist in a game company.

I would count coordination here as a deep technical skill, which requires a depth of study and/or experience. You are selling your coordination skills.

It's the stick of the T.

I don't think there are too many people around who actually have no deep skill. That usually doesn't hold up too well in the job market.
