Deprecating Safe Haskell, or heavily investing in it?
The most recent real case I remember is https://github.com/haskell/mtl/issues/110, which could ended badly.

Type class subsets
Splitting mtl classes into algebraic and non-algebraic components (url) Factor MonadReader into Ask (algebraic) and Local (non-algebraic) classes Factor MonadWriter into Tell (algebraic) and Listen/Pass (non-algebraic)

[ANN] mtl-2.3.1-rc1
It was the example from the ticket which works fine because there is no restriction that the argument to ContT r is a Monad

Draft mtl-2.3 migration guide
I don't think so, but here is a list of upcoming changes in mtl-3.0.
What are some alternatives?
parallel - a library for parallel programming
motor - Type-safe effectful state machines in Haskell
capability - Extensional capabilities and deriving combinators
eveff - Efficient Haskell effect handlers based on evidence translation.
mtl-unleashed - MonadReader and MonadState without the functional dependencies
control-monad-free - Free monads and monad transformers
time-warp
cond - Basic conditional operators with monadic variants.
effect-monad - Provides 'graded monads' and 'parameterised monads' to Haskell, enabling fine-grained reasoning about effects.
atl - Arrow Transformer Library
apecs - a fast, extensible, type driven Haskell ECS framework for games
mtl-uplift - A way to lift entire substacks of monad transformer stacks, boilerplate free!
