Yes, it's "just" a parser. It can still be used to "configure" NM via
/etc/network/interfaces, at least according to README.Debian (never
tried that):
Managed mode will make NetworkManager manage all devices and will make
NetworkManager honour all dhcp and static configurations for wired and
wireless devices.
Which means you should be able to keep using /etc/network/interfaces
for simple setup. ifupdown and friends will not work in that scenario,
or the other way around, obviously.

Yes, it's managed=false, sorry. That's the default in Debian AFAICT,
which means that /etc/network/interfaces takes precedence.
