I did a little JKD and am familiar with Chi Sao.
The problem I have with this is that when people clinch they use a lot of strong forward movements while WC traps tend to rely on lateral movement to pull you off line. Also these moves only work on the arms where as techniques like say and arm drag have the strength to move the whole upper body.
However, philosophically, keeping contact with your opponents limbs so that you can feel their movement rather than having to look at them is a good idea. The window for this is pretty small though I don't do judo specificly (nogi sub wrestling).
I'm actualy a little curious and plan on working some into my randori.
