I have done some work with the FLARM people in Switzerland on their obstacle databases; yes they do mark these types of wires.
I also am of the opinion that it is unrealistic to expect we can get all SWER ones in there, but key ones particularly in mountain regions where we fly closer to terrain is certainly a useful thing. If anyone has the stamina to go about hunting a source for the data, I am happy to help process the database for use in OzFLARM. Basically we just need lists of lat-lon and height of the obstacle relative to the terrain. (For wires this is done with polylines i.e. points in the same way.)
