As described in Issue 4551 there are indexes that uses the same first column or columns as the Primary Key indexes. This make them unnecessary. They only slow down DMLs and uses storage.
I commented, not deleted, them. But if you want I can delete. It is quite hard to test this, as nothing in application behavior will change.
