I never once felt the need to blow on a SNES cartridge either. I promise you, it was 100% only a NES thing.
In fact, the edge connector was never really the problem and blowing on it was never more than a placebo that actually did more harm than good. The real issue was the weird VCR-like insertion mechanism the NES used, and I’m pretty sure
the later top-loader version solved the problem even for NES cartridges.
