Joining the party late, my main use case for literate Haskell is
README.md files.  The solution I currently use is to have a symlink:

    README.lhs -> README.md

(see e.g. https://github.com/hspec/hspec-wai)

As I understand it the current proposal neither helps nor conflicts with
this use case/solution.

I leave this here as a comment mainly to indicated that:

 * the proposal as it stands does not solve my use case
 * there are other ways to solve this (namely: using symlinks)

Cheers,
