Henrik I meant it as everyone needs to contribute indirectly (via feedback) or directly. I think many non "design system designers" will need to contribute directly to the system for it to be the best it can be.

That being said, I will say having a "design system designer" is still important. It puts a leader / owner to the system. I've seen at other companies where there is no owner(s) and the system eventually dies.

That being said, there could be companies that prove me wrong!
