It is not clear what you mean by "interact" in AC4. Are you referring to the governing physical equations for interactions between objects (ie, collisions)? If this is the case than I believe that this anticipated change is related to AC11 (or the same as).
Also, I do not think that UC4 is an "unlikely change", it is a goal.
Lastly, UC6 and UC7 aren't related to design. They should be covered by the assumptions in your SRS. @smiths made a similar comment to some of my UCs during my presentation (that they are actually assumptions from SRS) . I think that UC6 and UC7 suffer from this same issue.
@smiths I am unable to create assignees .. Also this link from the repos has not been updated in months.
