I think that I might add, it is unnecessary use of muscles and joints and that such unnecessary movements should be avoided if possible.
It requires one to learn to coordinate upper arm and the pendulm swing at, and beyond, contact. Such precision required with the dropped elbow is unnecessary and can contribute to an unreliable stroke. Buddy Hall is one exception, however, this requires his talent and dedication.
Occam's razor should be applied here. http://en.wikipedia.org/wiki/Occam's_razor
It is useful as a training device that emphasises the need to follow through and as such may contribute to a "better" follow through for some people. However the price (see above) is probably too high.
It is generally needed if one believes that the cue tip should rest on the table at the completion of a shot. The pendulum swing, by it nature, results in the cue tip more elevated than at contact. However, it seems to me that "tip on the cloth" is a pool player's myth, except in so far as it contributes to a straight follow through.
I can equivocate more but those are a few possible additions that may contributes to the possibility of deciding to use or avoid the dropped elbow.
