I don=E2=80=99t really understand the problem with the Scheduler, and even
less its relation to backpressure.
Dealing with backpressure is a matter of queue implementation.
The Awaitable contract has nothing to do with this situation.

Confident about what exactly?
And what exactly would be the footgun?
These are very general statements.

It seems to me that people in this conference use the word =E2=80=9Cfootgun=
=E2=80=9D
far too often =E2=80=94 and not always in the right context.
There=E2=80=99s a lack of rational boundaries here.
Not every programmer=E2=80=99s mistake is a footgun.
Especially that:

```php
if (await($response)) {
  return await($response);
}
```
