Dunno if you're missing anything, but you're certainly not the only one
wondering. FWIW, for my purposes I've been using the function below ever
since I discovered `variable-at-point':
(defun .variable-at-point ()
"Sanitized version of the utterly [CENSORED] `variable-at-point'.
\(The latter returns 0 as the failure value. Very useful,
indeed.)"
(let ((v (variable-at-point)))
(unless (eq v 0) v)))
