Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

UnliftIO, ExceptT and Coercible
FWIW, your suggestion is very similar to a proposed instance for MonadUnliftIO (ExceptT e), except that effectfuls use of the type system means that it doesn't suffer from one of the proposed downsides (dubious interaction with catchAny).

How introduce `ResourceT` into my stack

Is `MonadBaseControl` dead?
Any way quoting u/snoyberg : https://github.com/fpco/unliftio/issues/17#issuecomment-363655106

Try.do is dangerous
That's not true. It's just writing that instance is a bit tricky: https://github.com/fpco/unliftio/issues/68

Try.do for recoverable errors in Haskell
However, ExceptT cannot be an instance of MonadUnliftIO – because it necessarily requires multiple exit points. See this discussion which should give you an idea of how hairy and unpredictable this can be.
What are some alternatives?
foldl - Composable, streaming, and efficient left folds
recursion-schemes - Generalized bananas, lenses and barbed wire
effect-monad - Provides 'graded monads' and 'parameterised monads' to Haskell, enabling fine-grained reasoning about effects.
lifted-base - IO operations from the base library lifted to any instance of MonadBase or MonadBaseControl
tardis
mmorph - Monad morphisms
capability - Extensional capabilities and deriving combinators
Workflow - re-startable monad that recover the execution state from a log, and workflow patterns
retry - Retry combinators for monadic actions that may fail
managed - A monad for managed values
distributed-closure - Serializable closures for distributed programming.
exceptional - A simple Haskell type for pure code that could go wrong.
