Thus, the question is: are there any transformers-specific features iteratee package needs, or can it just go with mtl?
I have successful build iteratee by replacing transformers with mtl in the .cabal file.
I suspect mtl to be more popular... And actual "popularity" can be measured.
Popularity is not the issue. The issue is that we are currently in a transition from using mtl to using transformers. See:

Are we? The first thread starts off cheering for monads-fd/tf and transformers, but fizzles out, as people consider the impact of breaking existing software. The other one is a post by Ganesh, which for all I know could be a statement of his personal position and seems less than authoritative as to the direction of the Haskell Platform as a whole. Perhaps I missed the memo, or perhaps I am just unclear as to which antecedent 'we' refers to in your statement. In any event, I don't mean this to sound nearly as confrontational as it probably does, but I didn't get the impression from either the initial thread or its brief resurgence that anything had been decided. -Edward Kmett
