Commented-out code may look like a defun.

The Emacs manual states

In modes where `open-paren-in-column-0-is-defun-start' is `t',
*don't put an opening delimiter at the left margin unless it is a defun
start*.

and you say `open-paren-in-column-0-is-defun-start' is obsolete ;-)

BTW, in Elisp an open bracket in column zero of a string should not
confuse Emacs.  Yet you highlight it with `font-lock-warning-face'.
