I'm not sure you got an answer to this question. Here is a simple use case.
Memory map a network endian file. Swap_in_place. Use.
You definitely don't want a copy in this case since your file could easily be very big. Think of the case where your file is huge (say 10Gb), you really don't want to perform a copy and swap since that puts your memory need at 20Gb instead of 10Gb.
