lax environment requirement when transforming a Handler

Env1 <: Env when transforming Routes / Handler seems too restrictive. Perhaps I'm missing something, but I see no reason why transformation can't change / eliminate it completely.

Failing build seems unrelated to my changes, I see it happens in other PRs too
