Depending on the frequency of checks, you might get many updates to the
zone. With every update the zone serial is incremented and the zone is
also updated on all of its slave servers.
This might be okay in a small setup. But you should be aware, that it
might have unexpected side effects on other setups.


Regards,
Matthias
