No, I don't think so:

   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

What part of what he said does _not_ confirm that he claims that omission
implicitly indicates to readers that the behavior is unpredictable and
unsupported?

And again:

> Well, [the doc string] does say that if you use a non-nil

The doc string says nothing explicit about non-nil and non-t.
His claim is that it says this implicitly, by omission.
