No, the cable recommendation is from Nintendo it self which goes with how they designed the Switch...
The dock bricking has nothing to do with the cable as most use the original Nintendo charger with them so its something with the dock (what some engineers claimed is there is probably voltage drops pushing the Switch a lot more or some crap like that, so voltage spikes)...
About Nintendo not following USB-C Specs, NO ONE DOES, there's a lot more devices out there using USB-C 15V too like laptops. Almost no manufacturer ever follow the USB specs so that's why you have brand X quick charge, brand Y quick charge (most are incompatible with other brands QC technologies) and quite a lot more amps going trough them than it was ever designed, specially USB 2.0 smartphones which was mostly common up to 0.5A and we see 2.1A and higher...
ps: But for data only and connected to like a PC USB2.0 0.5A port any USB-C cable will probably always work fine, now to charge at 15V or just high amps even at 5V, I would only use a certified USB-C cable my self (doesn't mean it has to be the expensive ones but rather certified).
