I do not like the intermediate result that is again wrapped inside EitherT to perform mapLeft.

In the future there is with real IO<E, A> which is coming up in 0.11. There you have an API to handle E, Throwable and A that is normalized and does not return the EitherT wrapper, until then what you have seems a legit alternative
