It seems this would have an adverse effect on protocol-aware connection
proxies: They would have to uncompress everything coming in and
recompress everything going out.

The alternative of compressing each packet individually would work much
better: A connection proxy could peek into the packet header and only
uncompress the (few, small) packets that it needs for state and routing.
