Additionally, it would be very useful to have the MaybeT monad transformer included into mtl-2.

While migrating my packages from transformers/monads-fd to the new mtl, the absence of MaybeT was the only problem I came across.

That would be going beyond the primary mission of replacing the existing mtl, though (and transformers still exports MaybeT).
