+- Packaging (poetry): Fix development dependencies
+
+  Per [Poetry's docs on managing dependencies] and `poetry check`, we had it wrong: Instead of using extras, we should create these:
+
+  ```toml
+  [tool.poetry.group.[group-name].dependencies]
+  dev-dependency = "1.0.0"
+  ```
+
+  Which we now do.
