Well, "broken" is an opinion, not a fact.  AFAIK they can work.  Maybe
not as efficiently as some other API, but that's a different question.

I'd urge you to try and find a way to make it work without such
a workaround.

Once you get it to work without the above workaround, you'll be able to
write a much better bug report.

Calling beginning-of-defun-function followed by end-of-defun-function
(and comparing the resulting position to the start position) should be
sufficient to let you know whether or not you're inside the function
whose definition starts most closely before point.
