I'm not aware of the kernel practice either, but if `t.Something` is
unusual in typical Python projects, I think this elaboration deserves to
be mentioned in the commit message.

Other than that, given that declaring all imports at the top is not
mandatory, I wonder if we could just conditionally import `ParamSpec` as
follows:

```
from typing import Any, Callable, TypeVar

T = TypeVar('T')
if sys.version_info < (3, 10):
    def wrapper(func: Callable[..., T]) -> Callable[..., T]:
        def wrapper(*args: Any, **kwargs: Any) -> T:
            return func(*args, **kwargs)
        return wrapper
else:
    from typing import ParamSpec

    P = ParamSpec('P')
    def wrapper(func: Callable[P, T]) -> Callable[P, T]:
        def wrapper(*args: P.args, **kwargs: P.kwargs) -> T:
            return func(*args, **kwargs)
        return wrapper
```

In this case, we don't need the `t.` prefix.
