Speaking from the Apache Tika  perspective, and from the perspective of other libraries and toolkits that detect
document formats and descriptions and so forth, relying on IANA, and MIME, and MIME extension (the x- or +)
would sure make it easier in our MIME detection system and improve our overall ability to parse content.
Solely for this reason, I'd VOTE for #4.
