It seems you simply don't understand the concept of backwards
compatibility.
RFC 2231 uses a subset of the format of RFC 2046, which means it *is*
compatible. It does not change the format for existing parameters, it
just defines new parameters with a ``special'' format.
And it might have been simpler just to add "'", "*" and "%" to tspecials,
for the removal of all confusion.
That would not be backwards compatible; it would change the format of
(unencoded) parameters.
