I don't think this is a critical issue, but another idea would be to simply 
have dired echo some kind of warning, suggesting to use the other method, and 
maybe referencing the manual.

The tricky part there, I think, is that the warning would get cleared from the 
echo area, by dired's progress messages, before the user had a chance to read 
or notice it. So I'm not sure if that would be useful in practice.
