FM2.0 supports the FDRMGRNONTRACEABLE model name on edges and junctions.
FM1.0 supports the FDRMGRNONTRACEABLE model name on edges only.
I am not aware of any ramifications to the network or fuses if the FDRMGRNONTRACEABLE is added to the fuse but remember that when the FDRMGRNONTRACEABLE attribute is set to YES, the feature is consider de-energized and will not be assigned a feederid. Having the ability to prevent tracing at the device level provides more granularity.
Hope this helps,
