fair point I expected they would some protection.... but you have missed the actual point that is its just not safe......
It's only unsafe if the mod can actually fire a nickel coil in a non-temperature controlled setting.
I think you'll find that the mods you listed simply couldn't fire a nickel coil at all. To get to .4 or .5ohms with nickel would require an absolutely huge coil. It's never going to fit in an atomizer. If you're wrapping around a 3mm drill bit you would need something along the lines of 60 wraps to get a .5ohm coil with nickel. That coil would be close to 2 inches long.
Nickel is a NON-RESISTANCE wire. It's not like Kanthal, it has very very little resistance. Even really big nickel coils are difficult to get over .15ohms. Most are in the .05-.12ohm range where almost nothing but a temperature controlled mod could fire them at all.
