It does not work with scp. I've rechecked it twice on different systems: if you truncate source file for scp, it still continue to copy data. It displays '-stalled-' state, but network activity is very high for very long time after the file was truncated.

Try yourself:

fallocate big -l 10G
scp big remote_server: &
truncate big --size 0

Check network interface load (atop utility, for example) right after that script. It will be very high until copy is not finished.
