It'll break loudly -- you will know. Do you want me to prototype & benchmark a couple dtype-agnostic versions? I don't think it would be that hard to do, and I suspect the performance impact would be modest if anything. If changing the spike dtype is something that might actually happen, I'd rather try to come up with a new kernel now while the details are fresh in my head from #4695 !
