No doubt, but it remains that if there was a suitable market for the same camera + no record limit, even if at a premium to compensate for taxes + extra work, vendors would take notice and put in the necessary effort to engineer their devices to compensate for the heat. Without a suitable market, though, why bother? Design them only to the point that they can record for ~30 minutes and the market says that's good enough.
