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.
