HTTP tests tend to be more cumbersome to set up and harder to debug
than the plain vanilla "over the pipe on the same machine"
transport, so I tend to agree with the statement.
They however represent a more common use case, so having HTTP tests
in addition to non-HTTP tests would be nicer, if we can afford to.
Thanks.
