If the machine in question has a desktop environment and NetworkManager (or equivalent), doesn't /etc/network/interfaces (or interfaces.d) config override nm (etc)?

I thought without eg. connman, a dropped connection on a wifi NIC configured in /etc/network/interfaces would not automatically be re-established, and that this config had to be removed (or commented-out) for something like NetworkManager or wicd to manage the connection, in the case of a DE.  Is that wrong?

Thanks,
