If I'm not mistaken IPSec gives you both compression and encryption. Just as an example.
True, but that setup (as well as any other hypothetical TCP/IP stack level solution) would require network tweaking on both server and the clients. With protocol-level compression you can avoid that altogether and encryption is already solved with use of TLS.
