There is an underlying flaw in that concept.  Many browsers and servers
today are passing or inferring non-utf-8 input from the URI or header fields.
Many are passing utf-8 data.  As the specification makes no preference
or definition, the server is responsible for inferring some meaning by the
context of the request by the client, and returning the response in kind.

Making such a change by fiat would be inappropriate.  Some additional
information has to be passed by the client to preempt any inference of
the high-bit octet codes.

If this were a change to the HTTP/1.2 specification, that would be the
indicator that all headers and the URI itself are utf-8 encoded.  Without
a bump of the HTTP version number, it's entirely out of scope.

I'm not clear here about Larry's intent, so I will ask;

Larry, did you mean for the next document revision to spell out an
HTTP/1.2 conformance?  If not, is Chris Haynes' proposal out of line,
if he introduces the appropriate header field definition to assert that
the client and server treat the now-opaque octets %80-%FF as utf-8?
