Well, if it works as claimed, then the technology allows the diver going deeper than normally, and there will be certainly individuals who will use it for going deeper than they would normally go.
But what Panos meant were decompression bents due to the ascent quicker than normally. This risk concerns freedivers who do frequent deep dives and it was discussed here often. Effects of freediving bents are known to Polynesian natives under the name
Taravana since centuries, and documented in modern times since 1958. Several high-profile freedivers suffered serious injury due to DCS - for example it is a very likely cause of the latest accident of
Carlos Coste, and we shouldn't also forget the accident of
Benjamim Franz in 2002. Many other freedivers experienced lighter DCS incidents during training or competitions.
Some freedivers, like for example
Eric Fattah, regulate their ascent speed and do also short decompression stop. Eric wrote about it many times here and suggested ascent regulations to AIDA too.
Although I imagine that it is not impossible (and hopefully not too difficult) to control the ascent speed with the BC belt (just as one can do it with scuba BC's), if the freediver is not properly trained and uses the BC belt as a simple lift, he may expose himself to serious additional risk of DCS.
I think you should work well on a training manual and a legal disclaimer warning about all different possible risks involved with using the BC belt.
