In the interest of understanding the scope of Controls features, I dumped the count of transforms being used.

Some of these transforms are complex and impossible to unscale. It would be nice to consolidate these where appropriate and retire the most complex ones that aren't needed.

Primary transform count:

SELECT ds.primary_index, td.transform_id, td.text, COUNT(*) instance_count
FROM pdb_transform_descr td
JOIN device_scaling ds
ON td.transform_id = ds.primary_index
WHERE td.prim_comm_transform = 'prim'
GROUP BY ds.primary_index, td.transform_id, td.text
ORDER BY ds.primary_index;

 primary_index transform_id text                                                         instance_count
