+# Adding `goth` to dependencies causes > 40 additional packages to be installed. Given
+# that dependency resolution in `poetry` is rather slow, we'd like to avoid installing
+# `goth` for example in a CI pipeline that only runs linters/unit tests, not integration
+# tests. Therefore we specify `goth` as an "extra" dependency, with `optional = "true"`.
+# It will be then installable with `poetry install -E integration-tests`.
+# Note that putting `goth` in `poetry.dev-dependencies` instead of `poetry.dependencies`
+# would not work: see https://github.com/python-poetry/poetry/issues/129.
