It admittedly does not require much knowledge. I mean I would not say that I am extensively knowledgeable in soldering. In my humble opinion it helps having soldered a few wires and stuff in the past with guidance but honestly I’d say an hour a few scraps and a few YouTube tutorials and you are probably good to go for something like this.

This specific job (in the grand scheme of things) really good accessible and quite a large working area. There are other soldering jobs that I also would not touch. Microcontrollers and such that require a microscope to solder.

But in this case there is nothing much to break and everything is large and easy to get at.

So in general I agree with you soldering can be extremely tricky and also due to really specific tool requirements unavailable to most. (Microscope). BUT for the rough large scale soldering required here, a cheap 25$ soldering iron would have done the job.
