Simply the fact that HTTP/1.x do not allow upgrades of defined methods
in this manner.

If this "partial PUT" is sent to a server that do not understand it
would result in breakage, therefore it can not be accepted as an
extension of the existing PUT method. Instead it needs to use a new
method, making sure that breakage do not occur if the request is
attepmted somewhere where it's not supported.
