It seems like the takeaway is not that galactic cluster anomalies support or break MOND, but that MOND is a way to reduce the general astroöbject mass anomaly problem to a modified gravity plus the cluster mass anomaly problem. This makes sense if the cluster anomaly is tractable (?) and there are no other problems created by MOND (the real question IMO). The problem then is that we want to have enough examples where MOND "works" that we don't think we'll run into another cluster anomaly. However, there aren't too many types of objects in the sky. So we either need very good numerical evidence for MOND in all other systems (unlikely) or a solution to the cluster anomaly which might not be too hard, unless MOND is actually wrong of course, and that's a risk you often face as a scientist.
