As much as this may sound like gatekeeping, if they can't perform a simple 12-pin solder or at least pay someone to do it, they shouldn't have access to custom firmware or software. As for it being a great way to kill the system, unless you do something stupid like melting a half foot of wire when trying to solder, most of it can be fixed easily. Hardmods are the safest solution since there's no risk of it fucking up your nand. With ALL 'permanent' softmod solutions, there is a higher chance of a fuckup than using a hardmod. It's not like TX doesn't test their hardware a ton before releasing it. And if there's a problematic piece of hardware in a batch, TX will replace it for you.
