> Can you please consider to add this functionality to BIND9?

Thank you for the submission; IMHO it's a good idea.

We'd need to update the documentation and add a regression test in
bind9/bin/tests/system/logfileconfig before committing it.  If you can help
with that, it might speed the process up, otherwise it will probably be a
while.
