I disagree. I have the same experience as Daniel Dawalibi, it does not
work (BIND 9.10.3-P4):

27-Apr-2016 16:22:43.351 dns_master_load: foobar.example:15: foobar.example: CNAME and other data

And if I delete the "other data" (the NS and the SOA records), it also
fails:

27-Apr-2016 16:24:16.410 zone foobar.example/IN: has 0 SOA records
27-Apr-2016 16:24:16.410 zone foobar.example/IN: has no NS records
27-Apr-2016 16:24:16.410 zone foobar.example/IN: not loaded due to errors.

But that's not the problem, the problem is that you can alias a domain
name with CNAME but not a zone name.
