I would strongly argue against including blaze-builder in the platform.
The whole point of the work Simon Meier (and Johan and myself) have done
over the last year or so with adding Builder into the bytestring package
was so that we could get a good implementation with a good API into the
platform (and in the appropriate place). It would be silly at this point
to confuse matters for users.

So I don't mind if there is an aeson-0.6.2.x or a 0.7.x release, so long
as it's using the bytestring builder and not blaze-builder. And of
course note that the current 2013.2 HP already includes bytestring-0.10
which has the new builder API.
