That sounds line a good thing to do.

Hmmmmmm.  Is this safe and will not cause problems by possibly
duplicated refnames that came from the command line and the ones
that came from for-each-ref iteration?  I am not saying the change
is problematic; it is just I haven't looked at this code for a long
time that the existing machinery is already designed to tolerate
duplicated input.

Thanks.
