I think the higher-ups made the right call in this instance, since there's a high chance that followup treatment would be required and keeping that within the same medical team that made the diagnosis would be better for the patient. There is some benefit for the patient in staying in a familiar environment, but if that environment is going to change anyway may as well make sure they're in the best possible position for subsequent care.
With that said, I don't think it's a bad thing to push to build experience when feasible. Just because something is not optimal doesn't mean it's bad, and I'm sure the patients themselves would appreciate knowing that their medical provider is doing their best to stay current.
