Any reasons why we have return Err(....into()) in some places and bail!(...) in other ones apart from historical?

I would say it's for historical reasons and lack of style enforcement (I always forget to use bail!). At some point we should migrate from error_chain to failure and we can do a cleanup to have more consistent error handling.
