No, I have never done that.

---------
root at ns1:/etc/bind/domeinen# dig any @localhost extensus.nl

; <<>> DiG 9.10.3-P4-Debian <<>> any @localhost extensus.nl

But... I think I found it:
----------
root at ns1:/etc/bind/domeinen# rndc flushtree extensus.nl
root at ns1:/usr/local/sbin# nslookup extensus.nl localhost
;; Got SERVFAIL reply from ::1, trying next server
Server:		localhost
Address:	127.0.0.1#53

** server can't find extensus.nl: SERVFAIL

root at ns1:/usr/local/sbin#
----------
