And the proposed edit merely says what the existing MAY implies.

+1

UTF-16, presumably.

No BOM is needed for that anyways.  One can unambiguously detect both,
the use of UTF-16 (and even UTF-32) and the byte endianness used.  At
any rate, for Internet purposes, we don't care one iota for any UTF
other than UTF-8, and we don't care about non-Unicode.  So, reject.
