Most of the points risen here would get a clear response with a

We already have/had such diagrams. Obviously, they did not provide
enough "clear responses". Note that OCP has nothing to do with "http |
data input |" and "data-output | http" parts. OCP Core has specific
wording about that. That wording replaced some of the figures that had
those parts in earlier OCP Core versions.

PS. What about protocol conversion, is that OPES?

It can be. An application proxy that does protocol conversion may
support OPES mechanisms and may be OPES-compliant. A decent HTTP proxy
today has to convert between HTTP and FTP (or even Gopher, WAIS,
etc.). I do not see why OPES proxies should be more limited than
existing HTTP proxies. If OCP is involved in protocol conversion, OCP
agents would have to negotiate/agree on how to specify
original/adapted protocols via application message metadata.
