Honestly pretty useless.
There are people that have held off updating for ages that have convinced themselves otherwise.
Heres the reality.
If you really want a cold boot, you can use a modchip or trinket, it is that simple.
If some exploit does eventually come that allows coldbooting through other methods, going directly between CFW & official FW is incredibly likely to get you banned anway.
If your happy with your current setup you can always leave it, but if you do want to update, you might aswell just update.
Honestly the only reason id keep it low personally, would be maybe to sell it on ebay.
Probably get some idiot pay 1000$ + thinking hes struck gold or something.
