(In my case I will also add Maybe and STM).

To be honest I also never used a stack of monad transformers that had
another base monad than IO. So I also don't see myself using it.

However I can imagine other people will use it or are already using it
(users of MonadLib for example) and I'm interested in their use-cases
and experiences.
