I don’t think that this follows; with this change ‘reload’ does The Right 
Thing, and that is consistent with almost everything else. The restart action 
on a nameserver, webserver, database etc. would be expected to drop requests 
during the restart. Similarly a restart of a hardware firewall would drop 
traffic whereas a config commit wouldn’t.

This is a major version change, I think it is completely reasonable to expect 
people to read the release notes before upgrading to it. It also doesn’t 
require a config change so much as admin behaviour change.
