Interesting reading, thanks for the link. My HO is that there wasn't an *overwhelming* reason to do one or the other (keep it or junk it); but seeing as this is security and there was nobody actually taking up the care and feeding of the feauture, it's probably OK that the decision fell to the drop end of the scales.

(Someone did volunteer to run an audit but I could't find any results; someone was using the feature but people offered what seems to've been a fair workaround; this was an opportunity to remove cruft.)
