You prefer mutable?
I find it weird (unless in very rare occasions) that the state of an object changes upon const reference passing.
Current we have Current*() and Get*() APIs, for device data, IR node and tensor data.
And the Get*() are the one which "must get" a given entity. So changing the state of the object is expected.

I don't really "prefer" it, but it's the lesser evil here. If the methods are at least logically const, but they happen to mutate some internal state or cache, I'm usually fine with making that mutable.
