Ah yes, now I remember - I've seen pics of that.
The only wrench in that is that it has to be set up /precisely/ to match with the swing of the bar, so any minute change of angle of the bridge, for whatever reason, would require a readjustment, otherwise it'll go just that tiny bit out of tune when the bar's locked into the holder.
It's just a stick-on thing though, isn't it? No screws required. But, I can see where someone would not want to put something with heavy adhesive onto the face of their instrument...
