No, the consumer-facing name is “SuperSpeed USB 5Gbps”.
Gen 1x2 has been deprecated as far as I understand, so there is no more ambiguity when just referring to modes by their maximum data rate.
USB 4 would make this even more complicated, but they fortunately have decided that 3x1 (20 Gbps just like 2x2) also does not get a marketing designation, so there’s also no more ambiguity there.
"Gen 1x2" wasn't deprecated because as a marketing term it was never a thing to begin with. And they recently dropped the whole "SuperSpeed" part so now it's just "USB 5Gbps".
