Do you see them as basic defining aspects of characters in the game, IOW, everyone has a Role of some kind, special ability and all. Its just that most NPCs are low rated and don't advance like PCs and major NPCs. Joe the Security guard is a Solo, but at +1 or so, Jane in the IT department have Interface at perhaps +1 or maybe +2 if she's the section head or something.
Or do you look at Roles as indicating something is special about that character? Not every thug with a gun is a Solo nor is everyone turns out a computer a Netrunner. They are the ones with the talent, dedication and drive to take their specialty to the edge of ability to pull off feats that are a step above what more mundane people in similar careers can pull off.
I tend to waver back and fourth on the issue.
