I hope so, but as I said, I can't tell since I've never used it.

FTR, the current definition is like this:

  (defun LaTeX--env-parse-args (args)
    "Helper function to insert arguments defined by ARGS."
    (save-excursion
      (LaTeX-find-matching-begin)
      (end-of-line)
      (let ((TeX-exit-mark (or TeX-exit-mark
                               (make-marker))))
        (TeX-parse-arguments args))))

My suggestion is actually this (I copied a wrong version in my last
message :-():

  (defun LaTeX--env-parse-args (args)
    "Helper function to insert arguments defined by ARGS."
    (let ((TeX-exit-mark (or TeX-exit-mark
                             (point-marker))))
      (LaTeX-find-matching-begin)
      (end-of-line)
      (TeX-parse-arguments args)
      (goto-char (marker-position TeX-exit-mark))
      (set-marker TeX-exit-mark nil)))

In your example above, the point will be indeed inside "{}" after 'C-c
C-e' with no query at all.  Compare these examples:

  (LaTeX-add-environments
   '("foo" LaTeX-env-args t)
   '("bar" LaTeX-env-args nil)
   '("baz" LaTeX-env-args "Title"))

C-c C-e foo RET gives (with * being point):

  \begin{foo}{*}

  \end{foo}

C-c C-e bar RET gives:

  \begin{bar}{}
    *
  \end{bar}

C-c C-e baz RET gives:

  \begin{baz}{}
    *
  \end{baz}

C-c C-e baz RET baz RET gives:

  \begin{baz}{baz}
    *
  \end{baz}

For me, t behaves as described in the manual "Insert empty braces, leave
point between the braces.".  Does the above make sense?

Not at all, I'm grateful that you're critical about code changes, please
don't stop this :-)
