Being the author of the initial patch, Marc has reminded me to submit any feedback I have on the abduco_force patch, which will supersede my contribution. I did initially think of using a -f option, but didn't think there would be a need for any other option to be forced. This is how I ended up using a capital C rather than a -f option.
That being said, I have no opposition to the abduco_force patch, as abduco will still offer the same functionality. I'm not one for getting precious over changes to command line options. Thanks -- Four word witty remark
