Proxies have been mostly put on top of an operating system's tcp/ip

Actually it *IS* a benefit. By eliminating direct packet flow you do not
need to care about bad things sneaking in TCP and below,  actually it is the only
way to *reliably* ensure that we see similar data on the firewall and the endpoint.

I agree, but I was just saying that using the TCP/IP stack of an OS is
simpler than building a "stripped down" stack that only supports the
proxy needs, non even including e.g. the option to route packets, or to
support the many protocols supported by most current OS.
