    Only if someone thinks the existence of BE and LE variants poses a
    security risk or constitutes statefulness in some way.

    Some people think "stateful" extends to multi-byte encodings, because
    you have to keep track of where you within the sequence (lead code unit,
    first trailing code unit, etc.). By that measure, UTF-32 is actually
    less stateful than -8 or -16.
