Description
In DM-7049, an set of datasets were moved from the HSC mapper to daf_butlerUtils. These are in exposures.yaml and datasets.yaml, and are now available to all cameraMapper subclasses (provided that there is an exposures or datasets section in their own Mapper.paf file.)
An RFC will be published for each Mapper describing possible additional changes:
1. Additional cleanup is required in each of the obs_*/policy/*Mapper.paf files to fully implement this move. Datasets which are not consistent with the new "shared" datasets need to be altered before they can be removed, but carefully, so as not to disturb the code which utilizes the mapper.
2. Identify datasets in each mappers which have the same function as a shared dataset, but a different name. If possible, these should be renamed and made consistent with the shared dataset.
3. Attempt discover datasets which are no longer in use and could be deleted.

I think that we can reduce the number of differences between HSC and the other mappers by considering these issues:
1. deepCoadd,* and deep_coadd.* are shared among the various mappers, including Hsc. But they differ in details, which I can detail more if you like. Should these all be the same, assuming Coadd processing should be the same for all mappers?
2. HSC has very few datasets names "diff" or "deepDiff", but the other mappers do. Do we expect these to be the same from mapper to mapper, assuming that most of these probably appear in the pipeline after the calexp creation. And why are they missing from HSC?
3. Most of the other mappers other than HSC have chiSquared.* and goodSeeing.* datasets which are completely missing in HSC. Are these datasets which can be removed?
