When?
Since around 1975.
We're talking about a patch to beginning-of-defun, right?
Beginning-of-defun has until now been defined by regexps.
I don't think we are talking about the same question.
beginning-of-defun has a customization feature involving regexps, but
that isn't the point I'm talking about. I'm talking about what it
actually did, which (normally) was to find an open-paren in column 0.
You asked what I meant by heuristic and I explained it to you.

The docstring of beginning-of-defun doesn't say anything about "toplevel".
So what?
AFAIK beginning-of-defun is a function in the same category as
forward-paragraph and things like that, which do not care much about the
global syntax state, but instead only pay attention to the immediately
surrounding text.
That is not how I think of it.
The original definition was to look for an open paren at top level.
But that was too slow, so I established the convention of assuming
that an open paren in column 0 would be taken as top level even if it
was not really at top level.
