It seems that currently scp just silently ignores command-line options
that it does not understand. That is surprising and possibly dangerous
or damageable (since once will expect the option to have been taken
into account).

It seems pretty standard for a tool to fail on unknown options, but
since that might break existing scripts, maybe starting with reporting
a warning would be the best compromise.
