I've seen it stated in this thread, but never explained, no. The only "explanation" I've seen is quotes of me saying that it has a performance impact (I guess it wasn't my brightest moment: it does have a performance impact, but that impact is the same that's paid by all users of the pdumper, so it can't be significant enough to stop installing this patch).
