Additional comment: Plenty of packages add their own scripts to /etc/network/if-*.d e.g. to set nameservers, dns-search paths and things like that. These are all broken when using network-manager due to the lack to set configuration variables.
Network-manager should mimic the ifup/down as much as possible to keep the other debian/ubuntu packages running.
