named-checkzone change of behaviour in 9.16.35

Summary

Hello,

Not sure this is a bug of feature change, but since it wasn't mentioned in the changelog I believe this was not expected:

named-checkzone text output has changed in 9.16.35 (haven't tested on other new branches).

I believe this comes from this commit : 80e66fbd

BIND version used

9.16.35

Steps to reproduce

Run named-checkzone on a valid zone.

What is the current bug behavior?

With 9.16.35 :

named-checkzone example.com named.example.com
zone example.com/IN: loaded serial 2022113010
OK
zone example.com/IN: final reference detached

What is the expected correct behavior?

With 9.16.34 :

named-checkzone example.com named.example.com
zone example.com/IN: loaded serial 2022113010
OK

Not sure this line is relevant when performing a checkzone, and I'm pretty sure there are a few systems that use named-checkzone are parsing the output when running checkzones.

Best regards,

Thibaud
