[Pdns-users] Why the rectify-zone? increase-serial?

Today one of my customers was complaining that his NODATA-proof is
failing after adding CAA-records to a signed domain.
I quickly rectified the zone, flushed the caches, all is well again.

This makes me think about the 'why' behind the rectify-zone command.

We've scripted triggers that rectify a zone after a customer changes
records, most probably that trigger failed in this case, but why
actually do we have to do this manually? Are there any situations
where we do NOT want to rectify-zone after a change? ;-)

Could this not be handled by some logic that compares the serial
to the last-rectified serial and rectifies it on the fly when needed?
This might not work for super huge zones perhaps, performance wise,
but i dont think i would notice anything in my workload. ;-)
