{* ../../docs_src/path_params/tutorial003_py39.py hl[6,11] *}

Otherwise, the path for `/users/{user_id}` would match also for `/users/me`, "thinking" that it's receiving a parameter `user_id` with a value of `"me"`.

Similarly, you cannot redefine a path operation:

{* ../../docs_src/path_params/tutorial003b_py39.py hl[6,11] *}

- The DRA device taints and toleration feature received a separate feature gate, `DRADeviceTaintRules`, which controlled support for `DeviceTaintRules`. This allowed disabling it while keeping `DRADeviceTaints` enabled so that tainting via `ResourceSlices` continued to work.
