I understand your view and appreciate it.  It's just that I arrived some time ago at the same position that Cael mentions.
I don't see all movement as good movement.  Some movement serves to temporarily appease at least some among those who are not accorded full rights, with the intention of dividing them and weakening their position.
If such an advisory panel were to be created, then the hierarchy could and would say that they were listening to women, that women now had a say in the process, and that the question of ordination was moot.  If the advisory panel were to advise against such a position, well, we all know what happens when an advisory panel in the Catholic Church does not say what the powers that be want to hear.
Movement towards equality is good.  Movement to sidestep and prevent equality is not good in my view.  I see this proposal as the latter.
