scp does report unknown options:

$ scp -X a: b:
scp: illegal option -- X
usage: scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i
identity_file]
           [-l limit] [-o ssh_option] [-P port] [-S program]
           [[user@]host1:]file1 ... [[user@]host2:]file2

It also reports --options options on OpenBSD:

$ scp --blah a: b:
scp: illegal option -- -
usage: scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i
identity_file]
           [-l limit] [-o ssh_option] [-P port] [-S program]
           [[user@]host1:]file1 ... [[user@]host2:]file2

I think what is happening that GNU getopt is swallowing the long
options before scp sees them. There isn't much scp could do here except
perhaps avoid the system getopt() for its own and I don't think this is
worth it.
