Do we have statistics on how many aliases we have compared to the redirects in Wikipedia and Wikiquote, especially for proper names? I'd suppose that all redirects have been imported by now.
Aliases are a rather efficient way to store redirects for names which are used in many forms. My only problem is that there is no way to add an alias for languages, e.g. Latin names of learned people; but I hope search does or will remedy by searching in all languages anyway.
