dangerous behaviour of scp

[Jacques Bouchard]

When you require a scp copy of more than 1 file to a destination that is 
not a directory, scp copy the last input file to the destination 
(version openssh-3.8.1p1).

Thus if you forget to specify the destination, the last file is 
_silently destroyed_.

I know that rcp exhibits the same behaviour but cp and rsync don't do 
anything in that case and _kindly_ warn you that you made a mistake:

cp: copying multiple files, but last argument `<file>' is not a directory
Try `cp --help' for more information.

ERROR: destination must be a directory when copying more than 1 file
rsync error: errors selecting input/output files, dirs (code 3) at 
main.c(371)
rsync: connection unexpectedly closed (8 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(359)

Why not that user-friendly behaviour for scp, which shouldn't make the 
same mistakes as rcp?

A user who is sad to have lost data with a "secure" command.
