We are miscommunicating.

Exactly. And that value can be non-nil, but also not t. That is the
change I see, and your doc string suggests that it is intentional.
Thus, we have a behavior change wrt to the value that the body of
eval-expression will see. And non-nil, non-t values have special
meaning there.
