I've read this too, my theory is that it probably used to be true on older packs but given the higher C ratings of today's batteries, I would imagine the tabs are much more robust. Of course, it's only a theory.
That said, I've had success with the salt water bath. It discharged a cell from ~3V down to a few tenths of a volt in 4 weeks.
