EXI is 'lossless', right? Trivially convertible back to plain XML? Not much downside then. Ideally the downside that it isn't human-readable shouldn't count for much. Technically that's true of HTTPS too. If it's treated as a communication channel, it shouldn't matter at all. I suppose it depends how good the tooling is. I get the impression it's not natively supported by web browsers.
