We cannot do that and still call it HTTP/1.1.  The protocol versioning
rules exist to prevent the HTTP-WG from screwing over early implementers
of the protocol, such that the protocol can be deployed and remain
interoperable even though some definitions and requirements will,
by necessity, change over time.
