I'd agree. It's more trouble than it's worth for the minor weight saving.
There is added risk of a snag, it ties itself in knots and it usually takes longer to get a belay that is suitable for this technique.
Much better to invest in an abseil device that you can use on double ropes (not trying to reignite the rack/stop debate
) plus, in having a double rope and you get an unrecoverable snag, you can possibly chop off a useful bit of your main rope to use in the rest of the trip.
