How accurate is the comparison with plant fasciation, for anyone who knows more? My experience with owning/growing fasciated succulents (usually referred to as "crested" by growers and collectors) has been that they're more challenging to grow in terms of risks of things like overwatering, but as far as I know that behavior doesn't necessarily impact their overall lifespan. Sometimes a crested specimen can also revert back to normal growth. Maybe that's tangential to the article itself, but it's something I'd be curious to find more information about.
