You are right that if you want to do this in a heterogeneous computing environment, one of the layouts is going to be "wrong" and require an extra step regardless of how you do this.
But ... (a) this is way less common than it was decades ago (rare use cases we are talking about here ) and (b) it seems to be addressed in a sensible way (i.e. Arrow defaults to little-endian, but you could swap it on a big-endian network). I think it includes utility functions for conversion also.
So the usual case incurs no overhead, and the corner cases are covered. I'm not sure exactly what you are complaining about, unless it's the lack of liberally sprinkling ("no deserialization in most use cases") or whatever around the comments?
