Is it possible to get a DatasetType reset/cleared for a Butler repo?

The thing I most worry about messing up when running in our shared repo setup is incorrectly registering a DatasetType, because those are global to the repo. Maybe the mistake is a typo, or maybe it’s just that after some more work I realized the DatasetType needs additional dimensions. I have great confidence I will do this when developing metrics for DIA stuff.

butler remove-dataset-type is what you use. This only works if you haven’t stored any datasets already using the wrong definition.
