Is there a way to restrict domain users from adding other members to a space?

If one user creates a Google Space, is there any way to restrict other members of the space from inviting people?  I want to be the only person that is able to add new members.

I 2nd this. What's the point of being and appointing space manager privilege if any added user within the space can add another domain users.
