Description
As many have said before, stacking multiple monad transformers can be quite inefficient, it'd be cool if we had some kind of story for supporting performant instances for different combination of mtl classes.
Oleg has already done some work in that regard with meow-mtl and at the start of the year, I've also played around with specialized instances at cats-mtl-special.

Research direction
Start by reviewing the issue's references to meow-mtl and cats-mtl-special to understand the proposed approach to performant instances. The issue does not name files, tests, or a concrete completion criterion, so the desired submodule design and validation would need to be established before implementation.
