I am currently in such a team where the lead strongly wanted to write everything in Effect. Me being functionally-leaning I embraced his choices, you can write very very clean applications in Effect.

One note is that Effect-ts is essentially the spiritual and de facto successor of fp-ts, which is quite popular, especially considering it caters to people that already know some functional programming.
