The reason PROXY makes sense for HAproxy and similar "plumbing"
proxies, is that they do no session-multiplexing to begin with, so
PROXY only has upsides for them: Send a prefix, then just move
For Varnish much richer feature set, PROXY between Varnish and the
backend has significant downsides.
The biggest downside is that that any V->BE connection can only
ever be used for requests coming from one single C->V connection.
(X-)Forwarded-For doesn't have that problem.
That said, it wouldn't be too hard to make it possible to send
PROXY to the backend.

Never attribute to malice what can adequately be explained by incompetence.
