Yes, but the HTTP at the outside of the remote-controlled user aggent
does not care about what happens inside the user agent.

What I propose is not a new mode of operation, it is operation as a
user agent.

My opinion is that wording which would allow a proxy to conspire with
the user agent and rewrite authentication headers _does_ compromise
the protocol: it compromises the trust relations encoded in the
protocol.  HTTP defines a proxy as an impartial, transparent
middle-man:  a proxy is supposed to be a reliable conduit, which both
parties at either end can trust to act in a certain well-behaved,
impartial way.
