Essentially we have the choice of producing full compatibility by keeping the separate type in mtl, in which case State from mtl is not State from transformers, or partial compatibility by re-exporting the transformers one.
Yes, we must choose between full compatibility with mtl and full compatibility with transformers. A quick implementation of the former is

The separate versions of State etc are present, but deprecated.
Cool. I've been been playing around with regression testing hackage following Duncan's blog post on the subject - I've got a baseline test running now and will try your mtl-compat out next, and then a variant with the transformers compatibility.
