I doubt that, imo most consumers would then just say "f**k it" and go for a cheaper ambidextrous option, the Kiro itself is a good example, 60€ for an A3050 is just insanely high, and unless there is some sort of commitment beforehand, as a brand i wouldnt even start a lefthand only mouse, a good example is the Deathadder which obv. changed its PCB Design from 3.5g to 4g to one without dedicated sidebutton PCB, so a brand new pcb would have been needed to accomodate sidebuttons on the right which apparently wasnt deemed as a feasible option.
