What I said was unlikely is that an option in ifupdown's configuration,
/e/n/i, would control NM's behaviour. It's the mere mention of the
interface there, as in   iface enp5s0 inet dhcp   that makes ifupdown
control it, and makes NM back off, AIUI.

Right, and so the default NM configuration (ifupdown plugin present,
news to me) and   [ifupdown] // managed=false   in the .conf file,
means that NM should not, by default, configure any interface
mentioned in /e/n/i. In the OP's case, the original /e/n/i:
-rw-r--r-- 1 root root  433 Oct  4 17:23 interfaces.orig
is big enough to hold a typical lo+eth+wlan configuration, which
we haven't seen yet.

Cheers,
David.
