No, the 6.6 gadts are nicer than the 6.8 gadts, but the common subset
is pretty large.  Duncan has the issue right: it's the desire to
reduce the number of dependencies that's at issue.  And as far as
bundled versions, it's the desire to *remove* a bundled version that's
apparently at issue.  I'm not sure why this is considered desirable,
but apparently some folks feel strongly about this.
