That's the problem, one major browser implements it, then they all need to. Then we have servers and browsers that become more and more complex, not that that isn't the case already. Thinking carefully about whether something is a good idea is important. Personally I think compressing data with LZMA or bzip2 will introduce a lot of latency, more then the time to send all the data unencrypted; then lets not talk about needlessly wasting server bandwidth to encrypt it (it all adds up). Then you have spdy, which implements compression at a protocol level.
