Scott,
You don't need to depend on Esri for that:

As a user of GDAL in some of our products I’m trying to find a
contact, probably/possibly at Esri, that could add a new entry for
Ceres that uses the oblate parameters defined here
<https://astropedia.astrogeology.usgs.gov/download/Docs/WGCCRE/WGCCRE2015reprint.pdf>
(487.3km, 446km). ESRI:104972 exists for the spherical definition (470
km).
Thanks,
Scott
