Yes it is. I would not mind about 406 or 405, but 407 introduce a loop 
here.

I don't feel you are right:

What about the case where 2 "servers" are sending back 501? In this
case, openser will modify it to become 407. That's a problem.

Just for information: from my knowledge, 5xx answers are UAS answers,
not dedicated to "proxy" -> they are dedicated to servers side which
might be endpoints (gateway...) from my point of view.

For example, there is no reason that an endpoint should not be able to
answer with "505 Version Not Supported" or "513 Message Too Large".

Any hint on where the code should be modified to get a different
behavior for this specific case?

tks,
