This option is the only reason we pull in a dependency on the shared `zlib` library. Unfortunately, we cannot use a pure Rust backend here because that one does not support configuring the window bits of the deflate algorithm which is used in the deflate websocket extension. Using websockets in libp2p is already crazy inefficient because you end up with double encryption when using `/wss` (which is enforced by browsers if your website is served via https). A good encryption algorithm like noise or TLS produces an output that looks completely random. Any attempt in compressing this is pretty much wasted CPU power. Thus, I think removing this configuration option does not really hurt and allows us to remove the dependency on the `zlib` shared library. Pull-Request: #3949.
