Yes, the deleted () index makes it full but may actually slow the query down in real life so you need to test it on realistic data to see if you should keep it or not.
Right. In my case, the percentage of deleted records is near none, so even though it's a BINARY index (smaller, more efficient), it may be a slow down since really no records deleted.
