Interesting point about the Rosetta integration. I wrote about it a year or so back. Not only would a Rosetta integration make it possible for us to be listed on a CeX like Coinbase, it would allow seamless interoperability between blockchains, in that it'd make transactions deployment from an interface outside the ecosystem completely possible.

Presently, though. I think its purpose for now is to just get listed on Coinbase. Who knows, maybe we'll find it useful when we get friendly with other chains.
