*   `tf.cond` emits a StatelessIf op if the branch functions are stateless and
    do not touch any resources.
*   `tf.cond`, `tf.while` and `if` and `while` in AutoGraph now accept a
    nonscalar predicate if has a single element. This does not affect non-V2
    control flow.
*   `tf.while_loop` emits a StatelessWhile op if the cond and body functions are

...all these parameters are required because the default value is `...` (Ellipsis).

But now it's possible and supported to just omit the default value, as would be done with Pydantic fields, and the parameters would still be required.

✨ For example, this is now supported:

```Python
from fastapi import Cookie, FastAPI, Header, Path, Query
