This is all regexp-based, so brace balancing is not the way you would
expect it. Or am I missing your point? This is currently what
`font-latex-set-syntactic-keywords' does:
(let ((...)
(verb-macros-with-braces
(and (fboundp 'LaTeX-verbatim-macros-with-braces)
(LaTeX-verbatim-macros-with-braces))))
(...)
(unless (= (length verb-macros-with-braces) 0)
(add-to-list
'font-latex-syntactic-keywords
`(,(concat "\\\\\\(?:" verb-macros-with-braces "\\)"
;; Some macros take an optional argument. This is
;; the same line as above for environments.
"\\(?:\\[[^][]*\\(?:\\[[^][]*\\][^][]*\\)*\\]\\)?"
"\\({\\).*?[^\\]\\(?:\\\\\\\\\\)*\\(}\\)")
(1 "|") (2 "|"))))
...)

Ok, this is indeed a valid use-case.

True, AUCTeX breaks with your code.
