It's basically the same reason why people still drive manual cars. We
mistakingly think we know better :)

I use it to explicitely send NOTIFY's when I see the primary is still
behind on what I have.

And for that too.

Oh, i didn't know that. Does nsd act on that information when it
receives such a notify such as not do an AXFR if it already has the zone
with that serial?

I also use nsd-xfer to grab zones that are not maintained by the local
nsd and then process the zones (add DS, SSHFP, etc and sign) and inject
the signed zones back into the local nsd.
