talk_to_blkback doesn't gather any backend features, it just publishes the features supported by the frontend, which AFAICT can be done at any time provided that it's before switching to state XenbusStateInitWait. Blkfront doesn't have to wait for the backend to switch to state XenbusStateInitWait before publishing the features supported by the frontend, which is what talk_to_blkback does.
