How about at least implementing the length hiding mitigation suggested by the BREACH paper http://breachattack.com/resources/BREACH%20-%20SSL,%20gone%20in%2030%20seconds.pdf by randomly interspersing flush commands into the data stream (description and example implementation https://github.com/wnyc/breach_buster)? It's not perfect but for some use cases better than having no compression at all.
