The wish list is useful for kicking around ideas that are only partly formed and for settings related ideas that might easily be adopted. You certainly can use the bug tracker for feature requests but ideaswhich are poorly thought out or presented are likely to be completely ignored. Often feature requests take some time to even be marked as new which is seemingly automatic for the category, they do not need to be confirmed the way bug reports do.
If you notice not all the wish list threads get directed to the bug tracker as feature requests and here is my interpretation of why: If one of the developers who actually frequents the forum see something that is relatively new and seems viable they will make a comment to post it on the tracker. That doesn't mean other ideas are particularly bad or this idea is guaranteed to go anywhere, it just means that at the time it struck them as fresh and reasonable.
Now as the news of the day says if you do not use the tracker you have no right to complain, it would be good if more people actually learned how to use the tracker, it is not difficult. At the same time if you are too timid to use it, posting in the wish list sometimes results in someone like me posting your idea on the tracker. This would not seem to be too optimal for you as I will likely write it in a way that suits me, but then I also usually link the wish list thread to what I post so your view will not be completely lost.
