Since mtl-split is not a drop-in replacement for mtl, we cannot expect a quick change from mtl to mtl-split in all the packages that currently import mtl. Thus we have to think about a route of transition and a package which can be installed in parallel to mtl is a first step, I think.
My understanding is that GHC will allow both to be installed, and allow packages that use transformers and those that use mtl to be used together in the same program. What you can't do is use both transformers and mtl directly in the same package, but that's no big loss.
If this is true, then I will no longer complain. What about Hugs and others?
