Quoting VIP6
https://github.com/varnishcache/varnish-cache/wiki/VIP6:-What-does-pipe-mean-in-Varnish5%3F

	We add a std.send_proxy_header() which can be called from vcl_pipe{}
	only.

I think whether or not a PROXY header gets added should be based on an attribute
of the chosen backend, anything else results in a blowup of VCL code.
