At least three:
1. Where external interface is created when device is attached.
2. User wants to test samba configuration on non-networked device.
3. In virtualised environment like Qubes, where Template has no network,
but VMs that use the template do.

Probably more.

I've tested a number of "network" services, and samba seems to be the
only one that requires an external interface at time of installation.
