You're right that config profiles were supposed to be a potential way of
learning about outbound proxies, and RFC6080 does have some text about
finding a local profile. I'm not sure I'd call it a robust mechanism - it
basically assumes that DHCP or static configuration is giving you a local
domain name (like via RFC3361 or at worst RFC2132), and then you subscribe
to the config profile at that domain - but if you can bootstrap from that,
you could use it to get a config profile from the local administrative
domain.

But to your solidity point: did anyone ever specify a config profile for
actually configuring outbound proxies? Or for anything else, really?
RFC6080 is probably another solution to consider for this problem space,
but as far as I can recall there'd still be work to do there.
