This would be shocking. One of the rationales for APFS existing is that 
the HFS foundation was played out for dealing with large directories 
efficiently. I haven't looked into the details (life is short...) but if 
APFS is *worse* than HFS{+,X} with large directories then Apple is in a 
worse state than I had thought...
