Thank you for raising this issue. I like the idea of increasing
flexibility of environment insertion facility.

Both solutions looks feasible.  ...Hm, how about this third one?

(defun LaTeX--env-foo (environment env-func &rest args)
  (funcall env-func environment)
  ;; Instead of the above line, maybe...
  ;; (if (symbolp env-func)
  ;;     (funcall env-func environment)
  ;;   ;; Allow (functionname arg1 arg2 ...) for env-func value:
  ;;   (apply (pop env-func) environment env-func))

  (when args
      (let ((TeX-exit-mark (or TeX-exit-mark
        (TeX-parse-arguments args)))))

I expect this usage:
  '("bar" LaTeX--env-foo LaTeX-env-label "XXX" ["YYY"])
