No, you don't need any of those. They have been built in for a long time.
Most of them in 9.11 even.
Look at the startup log and it will tell you the list of built-in empty
zones.
You can override any of them, if you need to. For example if you have to be
authoritative for 0.168.192.in-addr.arpa because you use that /24 and want
PTR records, for some reason.

Cheers, Greg
