You're probably right that Switch ASICs would not be able to do any
BTC stuff. But most of them do use hashes, MACs are in hash tables
often, balancing requires hashes. There is also somewhat hazy
definition what is ASIC and what is NPU, NPU boxes are large
collection of same chips, and chips are executing same software to
completion, they can do anything, just matter of how long it takes and
how effective they are doing it, they certainly wouldn't be practical
